 | 2026-11-10 | minor | M7, #2174: a text style binds a number variable to its weight (`style.bind {field: "fontWeight"}`): the style takes the face nearest the number and sets the `wght` axis, so static and variable fonts both follow; a face-name (string) binding and a weight binding replace each other, and the weight wins in a file carrying both. The style editor's weight menu offers number variables beside string ones. A number bound to a line height is applied in pixels, as the reference tool does, which a test now pins. Numbers unchanged.

A field is written only when it differs from its default (in a design file saved by Figma, a text at the defaults carries none of the four), and an instance override that goes back to the default clears it. The warning narrows to OpenType features, which the importer does not read from a `.fig`. Checked through the importer only, not in other software. |

-> **Last reviewed:** 2026-10-10 · **Last updated:** 2026-11-10 · **Change:** minor (M8: Scale tool handle drags pivot on the opposite handle whatever the origin, and the origin starts at the centre (measured in Figma's web app, 2026-11-09); M8: Tab while renaming the last layer wraps to the first row, measured in Figma's web app on 2026-11-12; the text caret takes the text's solid fill colour (#2156); the Rotation field shows and sets the rotation on the page, in frames and groups, through node.set absoluteRotation (#2196); the eyedropper picks a magnified image's pixel under the pointer, not a blend with its neighbours (#2189); Selection colors shows from one distinct colour when a selected layer has children, and from two otherwise, measured in Figma's web app on 2026-11-09 on a frame, a group and plain rectangles; the crosshair of the shape and Text tools is drawn dark with a white edge, so it shows on a white frame whatever the system's pointer style (#2198); a boolean group takes a corner radius (and smoothing) that rounds every sharp corner of its result (#2222); 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;

 |---|---|---|
+| 2026-11-11 | patch | M4, #2110: in vector edit mode, choosing Mirror angle or Mirror angle and length for a sharp point (two segments, no handles) makes it smooth, as measured in Figma: both handles on one line through the point, along `(B - A) / \|BA\|^2 + (C - B) / \|BC\|^2` (A and C the far ends of its segments), each 0.3905 x its own segment for angle, both 0.3905 x the shorter segment for angle and length (the factor is known to about three digits; the length rule is medium confidence); several selected points each become smooth. Open-path ends, points that already have a handle, points with a coincident neighbour, and points whose two far ends coincide (A = C, so the direction is zero) keep the old behaviour. Evidence: tests in `crates/engine/src/canvas/vectoredit/ops.rs` and `tests.rs` |
