-> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-11-10 · **Change:** minor (a text style binds a number variable to its weight (#2174); mind maps, first step: a first node with three children on curved branches, laid out again after every edit (`board.mindMap`, `board.mindMapAdd`, #2226); the handoff mode reads Developer Mode in the interface, its ids and saved fields unchanged; the left rail's and tab strip's icons are larger, 20 pt (#553); Suggest auto layout adds nested auto layout frames by rows and columns and keeps the placement of the design, as the help center describes (#1823); the Local variables window selects several variables (click, Shift+click for a range, Cmd/Ctrl+click to toggle, Escape to clear) and delete, move to a group and scope act on the selected local variables in one undo step (#2002); the desktop UI takes a system face for Ethiopic, Devanagari, Gurmukhi, Gujarati, Tamil, Telugu, Kannada and Malayalam, Sinhala, Lao, Myanmar, Khmer, Armenian and Georgian as it did for Hebrew and Arabic, so a String variable's Amharic value draws in the panels instead of boxes (#2014); a layer's effect binding takes only a field its effect has; ; the boolean operation menu leads each entry with an original icon (#2003); glass takes one sample instead of its dispersion window where the colours split under 1/256 px; glass bends towards its core, and rounded rectangles work it out in closed form; glass's light is a line on its bevel and splay turns the bend towards the centre; glass bends with a thick-lens profile and splits its colours over 8 steps; glass effects take variables and keep their frost within 0–100; web host bridge: `?host=parent` or `data-host="page"` hands a page the app's files, documented in the hosting guide; a connector end moved with Cmd/Ctrl held goes on any part of an object, and stays there as the object moves or resizes; a tap on a plugin panel's button keeps what was typed in its fields; a Dash cap setting (none, round or square) on Dash and Custom strokes, drawn on both ends of every dash; library analytics list how many layers and files use each style and variable; the Controller menu names each button as PlayStation and Switch controllers do; widgets draw lines and SVG pictures (plugin API 6); a connector end dropped along a side of a shape attaches to that side (#1708); regression tests pin a rounded shape's one-sided stroke and SVG ids and font families without XML-forbidden characters (#1351, #1124); a damaged image is refused with a reason instead of showing as an empty box (#1474); an image copied in another app pastes again on the desktop, and in the browser for the first time (#492); SwiftUI and Compose code names a bound variable by its iOS or Android code syntax; the colour picker's Image tab shows a placeholder and Upload from computer, an asset preview, and a file dropped on it replaces the image, keeping the fill mode, crop and position (#1682); the Frame tool's Phone presets have the iPhone 17 family (#1691); Show in folder works in the Flatpak build and selects the file on Linux (#1701); a dashed line starts and ends with a half-length dash, on the canvas and in exports; the Pages, Layers and Assets search fields keep their text in the middle of the field (#1703); a board connector's path can be reshaped by dragging its path handles (#1710); boards have 16 more shapes (arrows, polygons, star, plus and flowchart symbols), in pickers that lay them out in a grid; library analytics count insertions and show insertions and detachments over the past 30 days, 90 days or year; a stroke's Custom style takes a dash pattern of any length as a comma-separated list (#1681); a control request can set its own timeout, up to 10 minutes (`timeoutMs`; `figcraft-cli mcp --attach PORT --timeout SECONDS`) (#1696); gap 6: a widget opens its plugin's panel (plugin API 5), whose callbacks redraw it; the keyboard's Menu key opens the context menu, as Shift+F10 does; an Open link action can open in place of the prototype, with "Open in new tab" off (gap 15); a collection of this file can be extended (Extend collection on its row, `variable.extendCollection`), its extension following its edits at once, and extended collections extend again in the file; the eyedropper with Cmd/Ctrl+Shift makes a colour style or variable of what it picks; a live session's welcome sends the document compressed to clients that read it, about seven times smaller (#1665); a control request that times out says truthfully whether it was dropped or is still running and will take effect, and only screenshots and input blame the window (#1673); a board keeps earlier votes' results, listed newest first in Results and deleted one at a time; the object a stamp will stick to is outlined while the stamp tool is over it or a stamp is dragged over it, and board objects take no drops (gap 24); a server can list the files shared from it now for everyone who reaches it, Home ▸ Online shows them and their links carry no secret (`team_files`, part of #742); team library analytics count detached instances per component and file (gap 10); skipping the Open link notice by command is saved with the preferences at once (gap 15); a selected connector's bar on a board sets its start and end points, solid or dashed, its weight and any colour (#1596); cells copied from a spreadsheet paste onto a board as a table; a long layer name stays on one line in the Export button and the Dev Mode header, ending with an ellipsis, and no longer covers the Design panel (#1650); with hundreds of layers selected, the Design panel and the selection overlays stop going over the whole selection on every frame, so dragging 648 layers averages about 1.1 ms of UI per frame (#1571); plugin panels show pictures: an `image` control, base64 within 256 KB and 4,096 px a side, named by its label (gap 6); `.fig` connector labels without a saved snapshot are kept, centred on their line (gap 1); a drag moving many layers re-runs only what sits around them, not each layer's bindings, sizing, text and instance checks, on every move (#1571); damaged font tracking table offsets are checked instead of wrapping on 32-bit targets, and font indexing makes its existing offset bounds explicit (#1125); Bosnian (`bs`) draft catalog; text style dedupe is O(spans) via a last-two cache and fingerprint buckets (#1102); pasted layers whose image the clipboard lacks are named and show a placeholder that reads as missing (#1646); paint-style colours on layers pasted from another design app keep their style instead of turning black (#1638); progress docs cleaned of what merges left twice: rows merged into one, repeated status items removed, and `cargo xtask docs` (in `ci`) fails on a repeated table row or status item; a name typed for a variable or collection finds the one with that exact id before one named like it, and stored mode ids, font family variables and the panels' labels read exact ids (#1613); plugin widgets have hover styles: a layer's `hover` fill, stroke, opacity or text colour shows while the pointer is over it (gap 6); `.fig` elbowed and curved connectors without a saved path are routed like board connectors instead of drawn straight (gap 1); every file a command reads whole by path is a regular file within a cap that fits it: documents 16 GiB, placed images 256 MiB, CLI scripts 1 GiB; `figcraft-cli connect publish` publishes a code repository's code connect mappings to a design file (gap 16); while a drag only moves a large selection, its outlines, box, slots, spacing and Design panel values are worked out once and shifted, not rebuilt on every move (#1571); Shift+Cmd/Ctrl+Enter on a selected board shape adds the next shape already joined to it, and goes on typing (#1597); an imported or pasted file finds an installed family under the other names its fonts give it, and with other case and spacing, instead of reporting it missing (#1292); a development example generates figcraft-cli's shell completions and man pages from its clap definitions (part of #1396); `.fig` ZIP image reads share a total byte budget and count skipped images in the import warnings (#1076); German terminology corrections (M10): gradient stops, OpenType stylistic sets and the Home-screen preference; a component set's property rows fit the 240 px right panel: variant values wrap two to a line there and every + and − stays in view; the server key is checked by comparing SHA-256 hashes of the presented and the kept key, as the deployment guide says (#1130); opening a file contacts no team library server it names until you check it (#1097); a hostile server can no longer grow a client's memory with made-up people, and a session remembers a bounded number of deleted layer ids (#1121); `doc.list` gives AI agents and plugins the open files' names, not their paths (#1117); with a large selection, frames where nothing changed reuse the selection's outlines, box and slots and the Design panel's instance and position values instead of working them out again (#1571); team libraries and plugins larger than the 16 MiB download burst can be downloaded again, more slowly (#1089); a batch keeps one undo snapshot, not one per step (#1099); files nested 256 levels deep import on the browser's 1 MB stack (#1101); SVG and PDF exports count pattern sources and the renders they embed from the layer's depth, so one cap bounds a whole export (#1082); an explicit variables file path (`variable.import`, the `variables` of `file.open` and `file.import`) is refused past 256 MiB or when it isn't a regular file, as the sibling `variables.json` already was (part of #1114); joining and leaving a file nobody is editing reads and writes nothing on the server: it stays loaded a minute after everyone leaves (#1074); opening a `.figcraft` file unpacks at most 6 GiB in all (2 GiB in the browser), every area together (#1079); hovering the canvas hit-tests once per pointer move, not on every frame, and moving an auto layout frame no longer lays out its contents again on every move (#1571); `.fig` instance expansion no longer walks variable nodes for every instance or copies every outer override row into each nested instance (#1077); `comment.people` lists names that were only @mentioned, and `comment.next` and `comment.prompt` carry the mentions too (#1415); grid auto-placement looks for free cells a 64-bit word at a time and skips what blocks it, with the same placements (#1083); with the pen out, Enter or a double-click ends the path and edits the vector with the Move tool instead of drawing on (#1430); a recovery copy made while a version is previewed holds the file, not the version shown; a FigJam `.jam` file opens as a board (#1342); the Actions palette offers only commands that run from it, and no second row reading like a menu item: Place image opens the file dialog (#1574); share links can comment: a third access level beside edit and view, whose holder sees the file live and adds, replies to, reacts to and resolves comments but can't change the design; Preferences ▸ Scroll wheel zoom: a mouse wheel zooms the canvas about the pointer and Cmd/Ctrl+wheel scrolls (#1390); `comment.list {mentions}` lists only the threads that @mention a name (#1415); in the browser an internal error that stops the page keeps its unsaved files, which open again on reload (#1123); boolean operations refuse input past their caps, and a boolean group past them draws without its result (#1104); figcraft-cli parses its arguments with clap, following RFC-0012 (#1396); the selection and hover outlines of rounded rectangles and frames follow their corners (#1506); component properties keep the order they were made in when one is renamed, and Make slot asks for the slot's name first (#1536, #1537); the browser build publishes files to a server, so Share ▸ Online and Publish to server work there (#917); the browser build uses the fonts installed on the computer once asked, each read when text uses it (#1051); SVG import reads `color()` and `color-mix()` colours, with a note and a grey for those it can't (#1550); the portable Windows zip keeps its settings, recovery copies and plugins in `config\` beside the executable, starting with an installed copy's preferences; the window starts on other graphics when its first ones fail before the first frame: Direct3D 12 compiles with FXC and no device compiles wgpu's indirect-validation shaders, then Vulkan, OpenGL and lower requirements on the power-saving GPU (#965, #1438); Thai, Lao, Khmer and Burmese lines break between words (#1219); an AI agent attached over MCP shows where it works (#1416); a manual overlay's position can be dragged on the canvas (#405); one name for live sessions and comments: Preferences ▸ Your name, in the Join dialog too, kept in the browser, and a rename shows at once in the sessions you are in (#1380); requests that change a server's files have a budget per address, the server key's too, and join codes are found by their hash (#1075); the Join dialog shows a join from the click until its file is ready, with Cancel, and a failed join with Try again (#1381); SVG import draws each pattern tile once per scale, within the layer budget (#1080); Vietnamese letters typed with combining marks (decomposed) take one font that has every mark, instead of missing-glyph boxes beside the letter (#1478); comment.list reports each message's @mentions (#1415); mask groups draw only over the area they can paint, and nested isolated layers share one memory budget (#1061); components can't contain their own instances, directly or through other components; `edit.duplicate` returns an id map with `map: true` (#995); the batches kept for reconnecting apps are bounded in bytes by default, and `figcraft-server` takes `max_log_mb` (#1069); MCP and control calls name their document (#998); sibling placement in live sessions searches instead of counting (#1065); an AI agent attached over MCP comments under its own name, with an Agent label (#1414); the instance-swap menus have a search field (#1338); a refused batch's fixes take time linear in the batch (#1063); the connector tool shows the connector it will make while dragging, ends snapping to attach points (#1387); large images on the canvas draw from a smaller copy, so two 16k images no longer lag (#1483); a file's JPEG thumbnail can't crash the home screen (#1491's progressive JPEG check, now shared); `.fig` import: library text styles linked by asset key, and override rows restating a nested level (#1234); `.fig` import keeps the file's saved line breaks while the text and its box are unedited (#1236); Download a missing free font from the Missing fonts window (`font.download`, #754); the web build's wasm back under its 24 MiB gate (#1472); shadows of images with transparent pixels follow their alpha (#1289); Crop image: Object ▸ Crop image, the right-click menu and the image fill row enter crop mode (`image.crop`, #1464); offline Penpot 2.x import/export (#1143); optional batch continue-on-error with per-step outcomes (#1386); the Design panel's sections on one grid (#858); FigJam outer shape outlines and sticky body fallback beside author text (#1341, #1397); images placed at their own size, 2x screenshots in points (#1360); the toolbar on one 32 pt grid, without its Resources button (#1210); M4: zero-length round-capped dashes draw dots; dash expansion uses the existing safety budget; extracted from #1143; Arabic draft catalog; scaled instances keep their scale when their main is rebuilt (#922); .fig embedded images are copied once per blob, not once per hash (#1059); page ruler guides survive save and reopen (#1476); colour picker LCH and OKLCH models; non-ASCII layer names transliterate in code export (#1235); branches in live sessions and branch history entries, gap 17; plugin widgets take text input and a property menu (plugin API 4); boards: templates and tables; boards: a shared timer and voting sessions; boards: the dot grid, connector ends dragged to re-attach, curved connectors; Installed weights of an embedded font family (#1246); `.sketch` import, best effort (Sketch 48 and newer); CJK line breaking: JIS X 4051's line-start and line-end sets completed with the halfwidth small kana, the halfwidth and spacing (semi-)voiced sound marks, the iteration marks 〱–〵 and the halfwidth parentheses, with behaviour cases for each; Adobe Fonts found on macOS (#298); egui 0.37 hidden-capture deadline contract; Dev Mode measurements kept on the canvas and a read-only layers panel; boards: a board area row and progress entry; community fixes in #507, #510, #529 and #530: auto-save, a text box by dragging, batch step references, removing someone from a live session, Russian and Turkish catalogs reviewed, Czech and Indonesian drafts, the Japanese draft completed, zoom previews, the web clipboard, Alt-drag snapping and Cmd+D repeat, recovery copies, crash and rollback fixes, colour emoji, `.fig` import fixes;

 | 2026-11-10 | minor | M12, #2226 (step 1 of 4): mind maps in the document and engine. `board.mindMap` places a first node with three children on curved branches and `board.mindMapAdd` adds a child or a sibling; the normalize pass lays a touched map out again from its first node (88 between columns, 48 between siblings, stacks centred on their parents).

Since 2026-10-17 (community batches #727, #728): an instance's own identity and the cached library components a file carries, overrides applied by key and order, local text values and instance overrides over a shared text style, grid track sizes (fixed, content-sized, fill), slot content, labels of connectors saved with their drawn path (a static snapshot; the ends aren't live), skip ink, paragraph options and hanging lists, list start numbers, vertical trim, per-point stroke joins, editable text on a path, image adjustments and images carried in the message; since 2026-10-29, style links that name a library style by asset key and version (the file's own copy of it), with override rows above the linking one still winning, and override rows restating a nested level's overrides applied at that level, below the instance's own (#1234), and the line breaks the file saved with a text, followed until an edit or a resize could move one, or where a line would come out more than 3% wider than its box in the fonts at hand (#1236). Budgets come from the file's own size (four decoded values per compressed byte, 20M–128M, lower ceilings on 32-bit targets; the layer cap follows the file's size too), so a 15.4 MB synthetic file with 300,000 layers opens whole; ZIP image reads have a separate total budget of 4 GiB (1 GiB on 32-bit targets) of decompressed ZIP-member bytes containing encoded images, with the 256 MiB per-image cap kept: a member that cannot fit is skipped before its output buffer is allocated, and the import report names the budget and counts skipped images (#1076). Failed reads and invalid image contents still consume the bytes read; a reference used by several layers is read once. This is not a limit on decoded pixels or total import memory; images carried inside the message are unchanged. The file's bytes stay out of the command journal; an import report lists what was left out or changed once the file opens. Elbowed and curved connectors without a saved path are routed as FigCraft's board connectors are (right angles, or one curve, from the sides of the layers they join); an elbowed one saved with its path (`connectorControlPoints`: a point and an axis per run between the first and the last) keeps that path when it leaves and arrives by the ends' sides (#1910), and a curved one's saved `connectorBezierControlPoints` are not read; a connector routed here takes its line's paint, weight, cap and dashes from the file's generated line record, as one with a saved snapshot does (#1807). A connector's label without a saved snapshot is kept as text centred on its line, without its background. Not read: table cells beyond their own layers, live style and variable links for vector region fills, variables bound to fields the editor can't bind, video fills. Tested on fixtures generated in code (`crates/format/src/fig/tests.rs`, `tail_tests.rs` and the per-feature `*_tests.rs` beside them, fuzzed), `crates/engine/src/shapebuilder_region_paints_tests.rs`, and by reading back what the export writes; the FigJam report sample from #1341 checked locally only; no representative real-world corpus yet | read tail 5–10, write: checks against real files 5–15 |

Elbowed and curved connectors without a saved path are routed as FigCraft's board connectors are (right angles, or one curve, from the sides of the layers they join); an elbowed one saved with its path (`connectorControlPoints`: a point and an axis per run between the first and the last) keeps that path when it leaves and arrives by the ends' sides (#1910), and a curved one's saved `connectorBezierControlPoints` are not read; a connector routed here takes its line's paint, weight, cap and dashes from the file's generated line record, as one with a saved snapshot does (#1807). A connector's label without a saved snapshot is kept as text centred on its line, without its background. Not read: table cells beyond their own layers, live style and variable links for vector region fills, variables bound to fields the editor can't bind, video fills. Tested on fixtures generated in code (`crates/format/src/fig/tests.rs`, `tail_tests.rs` and the per-feature `*_tests.rs` beside them, fuzzed), `crates/engine/src/shapebuilder_region_paints_tests.rs`, and by reading back what the export writes; the FigJam report sample from #1341 checked locally only; no representative real-world corpus yet | read tail 5–10, write: checks against real files 5–15 |

Warnings: noise fills, OKLab and OKLCH gradients, motion and zoom blurs (drawn as plain blurs), fonts embedded with their data (not used), Smart Layout (kept as laid out), locked overrides, scaled instances. Tested on fixtures built in code (`crates/format/src/sketch/*_tests.rs`, fuzzed) and locally (`FIGCRAFT_SKETCH_SAMPLES`) on one real Sketch 50 file and the public Apache-2.0 IBM Carbon Design Kit saved by Sketch 68 and 83 (70,000 layers open in ~3 s, debug build; its edition saved by Sketch 47 is refused, as it should be); compared artboard by artboard with Sketch 2026's own renders (`FIGCRAFT_SKETCHTOOL`, black-box): the Sketch 50 file's 73 artboards differ in at most 2.3% of their pixels (0.8% on average) (text metrics, fonts FigCraft doesn't find, antialiasing), Carbon 11's 69 1.1% on average and at most 4.4% (text in IBM Plex, which the file embeds and FigCraft doesn't use yet), a Sketch 64 file's 65 artboards 2.1% on average, a Sketch 2026 showcase file's 16 frames 0.9% on average (at most 1.9%); the rules for master backgrounds, symbol clipping, mask opacity, bitmap fills, image overrides, stretching stacks, blur radii, colour adjustments, gradient interpolation and text growth checked against Sketch's renders of files built for each case (black-box, synthetic) | 5–10 (Smart Layout as auto layout, motion and zoom blurs, several borders of different widths; fonts embedded in the file once `.figcraft` documents can carry fonts: until then they would only last the session). Known limitations: a plain group (not a frame) that fills a stack keeps its layers' size where Sketch stretches them; a font Sketch can't find draws in the installed family's own weight (Sketch falls back to a regular face); text in the system SF Pro comes out a few percent narrower than Sketch's; macOS's reserved system fonts (PingFang) aren't found; brightness past about +0.4 is approximated (image filters can't add); OKLab gradients become sRGB stops (FigCraft gradients mix in sRGB) |

 # FigCraft parity with Figma
 
-> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-11-11 · **Change:** minor (the Point section's X and Y in vector edit mode show Mixed and set every selected point of the layer being edited, as in Figma; grid Fill (`fr`) tracks share the space of a fixed-size axis by their fractions and let a fixed-size child overflow, as measured in Figma (300 x 200, two rows, 100 x 150 and 100 x 20 children: rows 100 / 100, second child at y 100; with a row gap of 10, rows 95 / 95 and y 105; on Hug the rows fit their content, 150 / 20) -- this replaces the 2026-10-11 rule from the documentation; an exported layer with a background blur or glass keeps the blurred content behind it within its bounds (#2213); a typed number and a full stop at the start of a paragraph starts a numbered list at that number, as measured in Figma 2026-11-11; justified Chinese, Japanese and Korean text, written without spaces, spreads each line's room between its characters so its right edge aligns (#1970); joining the two ends of a path broken open by a deleted point closes it again, so its fill and selection outline follow the new segment and its corner radius instead of a straight line across the gap (#1951); glass's docs say which centre splay bends away from and where a shape gets no core; glass bends towards its core, rounded rectangles in closed form; glass's light is a line on its bevel and splay turns the bend towards the centre; glass bends with a thick-lens profile and splits its colours over 8 steps, measured against the reference tool; bulleted lists use the same bullet at every level of indentation, as the help center says, instead of a white bullet and a square at the deeper levels; typing `1)` and a space at the start of a paragraph starts a numbered list, as `1.` does, both being the help center's creation characters; a link on text is underlined by default, as the help center says, and Underline takes the underline off while the link stays; a Dash cap setting (none, round or square) on Dash and Custom strokes, drawn on both ends of every dash; gap 6: widgets draw lines and SVG pictures (plugin API 6); gap 6: a widget opens its plugin's panel (plugin API 5), whose callbacks redraw it; the browser build uses the fonts installed on the computer once asked, each read when text uses it (#1051); plugin widgets have hover styles: a layer's `hover` fill, stroke, opacity or text colour shows while the pointer is over it (gap 6); Thai, Lao, Khmer and Burmese lines break between words (#1219); MCP and control calls name their document (#998); shadows of images with transparent pixels follow their alpha (#1289); Arabic draft catalog; truncated text fills its last line before the ellipsis and keeps truncating when resized; auto-height text with max lines (#1375, #1376, #1377), numbers unchanged; plugin widgets take text input and a property menu (plugin API 4);

with a row gap of 10, rows 95 / 95 and y 105; on Hug the rows fit their content, 150 / 20) -- this replaces the 2026-10-11 rule from the documentation; an exported layer with a background blur or glass keeps the blurred content behind it within its bounds (#2213); a typed number and a full stop at the start of a paragraph starts a numbered list at that number, as measured in Figma 2026-11-11; justified Chinese, Japanese and Korean text, written without spaces, spreads each line's room between its characters so its right edge aligns (#1970); joining the two ends of a path broken open by a deleted point closes it again, so its fill and selection outline follow the new segment and its corner radius instead of a straight line across the gap (#1951); glass's docs say which centre splay bends away from and where a shape gets no core; glass bends towards its core, rounded rectangles in closed form; glass's light is a line on its bevel and splay turns the bend towards the centre; glass bends with a thick-lens profile and splits its colours over 8 steps, measured against the reference tool; bulleted lists use the same bullet at every level of indentation, as the help center says, instead of a white bullet and a square at the deeper levels; typing `1)` and a space at the start of a paragraph starts a numbered list, as `1.` does, both being the help center's creation characters; a link on text is underlined by default, as the help center says, and Underline takes the underline off while the link stays; a Dash cap setting (none, round or square) on Dash and Custom strokes, drawn on both ends of every dash; gap 6: widgets draw lines and SVG pictures (plugin API 6); gap 6: a widget opens its plugin's panel (plugin API 5), whose callbacks redraw it; the browser build uses the fonts installed on the computer once asked, each read when text uses it (#1051); plugin widgets have hover styles: a layer's `hover` fill, stroke, opacity or text colour shows while the pointer is over it (gap 6);

 # UI and interaction parity
 
-> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-11-10 · **Change:** minor (the Point section's X and Y in vector edit mode show Mixed and set every selected point of the layer being edited, as in Figma; Preferences ▸ Invert zoom direction reverses wheel zoom, pinch unchanged (#2145); Shift while rotating lands on absolute multiples of 15°, measured in Figma; Flatten bakes a vector's point corner radius into its path (#2195); a click on a fill, stroke or effect row's grip or background highlights it, Cmd/Ctrl+C copies that paint or effect and Cmd/Ctrl+V pastes it onto the selected layers, as the help center's Copy and paste properties between layers says (#1494); wrap style per paragraph and in text styles (#1827); the Annotation tool (Shift+T, `tool.annotation {id?}`): with a layer selected (or an `id`) it asks the UI for that layer's note at once, and in the tool a press on a layer selects it and asks for its note, a press on empty canvas does nothing; the marquee follows Figma's measured rules: a partly covered frame or section gives the layers in it the marquee touches, a rotated shape is touched by its outline, a drag from inside a frame selects that frame only when the marquee also takes another top-level frame (then whole) (`marquee_behaviour_tests`); copy, cut and paste in vector edit mode act on the selected points and segments (#1875); M8, #2146: K focuses the Scale tool's factor field with its text selected, so K, 2, Enter scales the selection by two about the panel's origin (FigCraft's starts at the top left; Figma's grid starts at the centre, left for a follow-up because the origin also sets where a handle drag pivots, which is not measured) in one undo step, after which the tool returns to Move with the selection kept; Escape in the field closes it with the tool back on Move and nothing changed (measured in Figma's web app, 2026-11-09; `pressing_k_focuses_the_scale_field_with_its_text_selected`, `k_two_enter_scales_the_selection_by_two`, `escape_in_the_scale_field_closes_it_and_changes_nothing`); the main menu and its submenus stay inside the window, moving up to fit and scrolling when taller (#2217); locked layers ignore the arrow keys and a locked parent's children can't be locked on their own (#1560); the left rail's and tab strip's icons are larger, 20 pt (#553); pick select: Tab while the keyboard selection box shows (or the chord again) puts a pink outline on a layer and the keys walk the layer tree from it, as Accessibility at Figma says (#1836); scrubbing a field faster or slower by the pointer's height, with a notice of the speed, as the help center's Scrub fields says (#1837); component rows in the Layers panel at AA contrast in the theme's component tint, with the rows inside a selected component in a tone of its row (#1903); Cmd/Ctrl-click on a padding field sets all four sides with the value typed, a documented auto layout shortcut; a fill per region of a vector: with regions selected in edit mode, the Fill section and the fill commands edit those regions' own fills, as Edit vector layers says (#1875); the Fill section of a text whose characters were coloured differently while editing shows mixed content, characters that all share fills the layer doesn't have show those, and a layer-level fill edit reaches every character (#1856); a number field scrubs when dragged with Alt held, as the help center's scrub section says, not only by its label; reuse visible layer selection roots (M8); ; with a shape or frame tool chosen and nothing selected, the arrows show a placement crosshair in the middle of the view and move it, and Enter places there, as Accessibility at Figma says (#1839); text direction per paragraph: Text ▸ Text direction forces a paragraph left to right or right to left, as Add right-to-left text says (#1830), with `text.direction`, `node.set textDirection`, the Type settings control once a right-to-left script is in the text, inspect, the CSS `direction` and the `.fig` lines' `sourceDirectionality`; the boolean operation menu in the Design panel leads each entry with an original icon drawn in code, a filled preview of the result (#2003); a press on the open gradient's handles or stops on the canvas keeps the colour picker open through the drag, as its own control (#1852); a click with the Bend tool on a sharp point curves it, its handles along the line between its neighbours, as Edit vector layers says (#1875); wrap style: Auto, Balance and Pretty on a text layer decide where its lines break, as Explore text properties says (#1827), with the Type settings control, `text.wrapStyle`, `node.set wrapStyle`, inspect and the CSS `text-wrap`; Backspace or Delete at the start of a list item keeps the item's indentation level, as the lists article says; max lines on auto-width text keep it auto width, hugging that many lines, as the text properties article says; superscript and subscript are synthesised where the font has no glyphs for them, from the standard glyphs shrunk and shifted by the font's OS/2 metrics, and a run mixing available and unavailable glyphs is synthesised whole, as Explore text properties says (#1828); Alt+Enter while editing text opens the link at the caret, as the accessibility page documents; Minimize, by its shortcut or the button by the file name, collapses the navigation bar and both sidebars as the help center says, with the right sidebar back while something is selected (#1835); the interface size keys of the help center's accessibility page: Cmd/Ctrl+Shift+Alt with =, - and 0 step the interface through the Preferences sizes and back to the system's size; Cmd/Ctrl+Alt+arrows rotate the selection a degree at a time, 15 with Shift, as the help center's accessibility page says; they resized before; the Layers panel answers Ctrl+1 as well as Alt+1 on Windows and Linux, the two keys the help center gives it; the colour picker's Image tab shows a placeholder and Upload from computer, an asset preview, and a file dropped on it replaces the image, keeping the fill mode, crop and position (#1682); the keyboard's Menu key opens the context menu, as Shift+F10 does; the eyedropper with Cmd/Ctrl+Shift makes a colour style or variable of what it picks; sidebar number and text fields keep their text vertically centered when focused, including typography spacing; with the pen out, Enter or a double-click ends the path and edits the vector with the Move tool instead of drawing on (#1430); the Actions palette offers only commands that run from it, and no second row reading like a menu item: Place image opens the file dialog (#1574); Preferences ▸ Scroll wheel zoom: a mouse wheel zooms the canvas about the pointer and Cmd/Ctrl+wheel scrolls (#1390); boolean operations refuse input past their caps, and a boolean group past them draws without its result (#1104); the selection and hover outlines of rounded rectangles and frames follow their corners (#1506); colour picker review fixes for text undo, fitted sidebars, moving controls and gradient variables; Corner smoothing: an original icon and the shared number-field drag gesture, preserving fractional baselines; guides snap to layers when dragged; Crop image: Object ▸ Crop image, the right-click menu and the image fill row enter crop mode (`image.crop`, #1464); the Design panel's sections on one grid — 16 / 8 margins, 88 + 8 + 88 + 8 + 24 columns, 24 pt rows, 4 pt between a row's buttons (#858);

 | Text: wrap style (Auto, Balance, Pretty) | done | per text layer (`wrapStyle` on `node.set`, `text.wrapStyle`, the Type settings control under Vertical trim, inspect, CSS `text-wrap: balance` or `pretty`): Auto breaks greedily; Balance narrows each paragraph as far as it goes without another line, so its lines come out close to the same length (what browsers do for `text-wrap: balance`); Pretty keeps lines full and, when the last line is one word, narrows one of the last four lines just enough to give a word to the lines after it (Explore text properties: "Auto: Figma fits as many words as possible on each line before wrapping to the next", "Balance: Figma distributes text as evenly as possible across every line, so each line is close to the same length", "Pretty: Figma keeps each line full, but adjusts the last four lines to avoid an orphan"). Saved line breaks from a file still win. At three levels (the text layer, a paragraph and a text style, per Explore text properties): the paragraph level is the caret's or the selection's paragraphs while editing (`text.wrapStyle`; the control follows them), or `start`/`end` on `node.set wrapStyle` (a paragraph's own style beats the layer's; setting the layer sets every paragraph again; Enter carries it to the new paragraph; inspect reports `lineWrapStyles` when paragraphs differ and CSS `text-wrap` only when they agree); the text-style level is a style's `wrapStyle` (shown read-only in the style editor, applied with the style, moved by `style.update`, unlinking when edited). The `.fig` import/export mapping stays open (#1827): a `.fig` export leaves the wrap styles out and a `.fig` import reads every text as Auto, so the wrap styles are lost through a `.fig` round trip. Test: `text_behaviour_tests::wrap_style_per_paragraph_overrides_the_layers`, `styles_behaviour_tests::text_styles_carry_the_wrap_style`, `text_behaviour_tests::balance_and_pretty_wrap_styles_break_lines_as_documented` |
 | Text: direction override (Text ▸ Text direction) | done | per paragraph (`ParaList::direction`: auto, ltr, rtl): Text ▸ Text direction ▸ Auto / Left to right / Right to left and `text.direction {direction, ids?}` set the edited paragraphs while editing, else every paragraph of the selected texts; `node.set textDirection` the layer's (or the chars `start`/`end` name); the Type settings control appears once a right-to-left script is in the text or a direction is forced; inspect reports `textDirection` when the paragraphs agree and `lineDirections` otherwise; Developer Mode's CSS writes `direction: ltr` or `rtl` when every paragraph is forced the same way (with `text-align: left` beside `rtl`, as Left is absolute on the canvas); `.fig` import and export carry each line's `sourceDirectionality`, read up to the paragraph count. Layout gives the paragraph its base level, so a forced right-to-left paragraph of Latin letters starts at the right, mirrors its list gutter and indent and orders its runs right to left, and a forced left-to-right paragraph of Hebrew the other way ("By default, Figma automatically handles text direction based on language detection. However, controls are available to override text direction per paragraph", "Go to Text > Text direction. Select Left to right or Right to left", Add right-to-left text). Not included: a direction in text styles (the article names none). Tests: `text_behaviour_tests::text_direction_is_forced_per_paragraph`, `fig::text_direction_tests` |
