+| 2026-11-12 | minor | M6, #2297: the `.fig` exporter writes an image paint's adjustments as `paintFilter` (seven fields: exposure, contrast, vibrance from saturation, temperature, tint, highlights, shadows; the tint's sign is flipped, as the importer reads it), and no longer warns about them; the importer already read them. Not checked in other software |
 | 2026-11-12 | patch | M6, #2273: `.fig` import: a numbered list keeps its start only on the item where it starts counting. Figma writes the start on every line of the list (measured in Figma's web app, 2026-11-12, from a saved .fig: a list started at 5 has `listStartOffset` 4 on all its lines, and after Backspace takes a middle item out of the list, the item after it starts a new list and is written with 0), so reading every line's value restarted the items after a split at the old start. The export is unchanged and a re-import now equals what went in; REST `listStartOffsets` read the same way |
 | 2026-11-13 | minor | M6, #2326: `.fig` export writes a page's prototype background (the file's `prototypeBackgroundColor`, field 141, a plain colour, written for every page, so Figma shows the same colour and not its own default for a page at FigCraft's default), measured on a synthetic file saved from Figma's web app. The colour is written opaque, as that file has it and as the importer reads it; a background that isn't opaque gets a warning for its opacity. The device warning now fires only for the page's device settings (device, rotation, colour, custom size, responsive), which stay left out. Checked through the importer only, not in other software. Numbers unchanged. |
 | 2026-11-12 | minor | M6, #2305: the `.fig` export writes a text's list spacing (`listSpacing`), hanging punctuation (`hangingPunctuation`), hanging lists (`hangingList`) and vertical trim (`leadingTrim`: none or cap height), which the importer already read. 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. |

 | Deep select (Cmd/Ctrl-click, Cmd/Ctrl-marquee) | done | |
 | Select layer menu (every layer under the click) | done | |
 | Escape with layers selected | done | clears the selection at once, whatever the nesting; it never selects the parent. Measured in the Figma web app (2026-11-08) with a rectangle in a group in a frame, selected from the canvas (a double-click into the group), from the Layers panel, and after Tab moved the selection to its sibling: one Escape selects nothing, a second leaves nothing selected. Escape still leaves text and vector editing, ends gestures and the pen first, and ends the focus view once nothing or the focused frame is selected (`selection_behaviour_tests`, `devfocus_tests`) |
 | Enter / Shift+Enter (children / parent), Tab / Shift+Tab (siblings) | done | Tab renames the next layer while renaming |
-| Resize handles: Shift keeps proportions, Alt from centre, constraints-aware | done | Alt shrinks too; past an edge flips (several layers mirror); groups and mixed rotations scale each layer along its own axes, keeping rotation and flip (no skew: children turned off a right angle are approximate); Cmd/Ctrl ignores a frame's constraints (`transform_behaviour_tests`) |
+| Resize handles: Shift keeps proportions, Alt from centre, constraints-aware | done | Alt shrinks too; past an edge flips (several layers mirror); groups and mixed rotations scale each layer along its own axes, keeping rotation and flip (no skew: children turned off a right angle are approximate); Cmd/Ctrl ignores a frame's constraints (`transform_behaviour_tests`); Shift keeps the ratio (a corner by the axis dragged most, an edge scaling the other axis about the opposite edge's middle), Alt keeps the centre, Shift+Alt does both, each read afresh on every move (`handle_drags_resize_by_the_documented_rules`; measured in Figma's web app, 2026-11-08; Ctrl/Cmd while dragging not measurable) |
 | Rotate just outside a corner; Shift in 15° steps | done | rotated handle box when layers share a rotation; the Rotation field shows and sets the rotation on the page (its own angle plus its parents'), in frames and groups alike, measured in Figma's web app 2026-11-10 (#2196): a rectangle drawn inside a turned frame reads 0, typing 7 makes it 7 on the page; the panel sends `node.set absoluteRotation`, while `rotation` stays the angle to the parent for scripts, inspect, codegen and the formats. Pinned, not measured: several layers read one value when their page angles agree (typing sets them all, one undo step); a flipped layer reads in the same form as before (a horizontal flip reads 180 plus the angle) and typing keeps the flip; a flipped parent is handled by the world math. Tests: `absolute_rotation_sets_the_rotation_on_the_page_keeping_the_centre`, `the_absolute_rotation_key_turns_about_a_moved_origin_too`, `the_rotation_field_shows_and_sets_the_rotation_on_the_page` |
 | Rotate just outside a corner; Shift in 15° steps | done | rotated handle box when layers share a rotation; Shift lands the rotation on multiples of 15° (measured in Figma: a layer at 7° or -4.27° ends at 15°), not 15° steps from where the drag began; layers with different rotations step the turn from 0 |
 | Flip, rotate 90° | done | |
 | Rotation origin (Alt+R) | done | a handle at the selection's centre to drag (snaps to the box's corners, edge middles and centre), double-click puts it back, Escape or Alt+R hides it; the corner handles, the rotation field, Rotate 90°/180° and `transform.rotate` turn about it; it follows the layers and lasts as long as the selection, not saved (the documentation doesn't say; pinned) |
 | Enter with a shape or frame tool chosen | done | places what a click makes (100×100, lines 100 long, sections 400×300) in the middle of the view, selected (`tool.place`); from the toolbar, Enter on the chosen tool. With nothing selected, the arrows first show a crosshair in the middle of the view and then move it by the nudge amounts (`tool.crosshair`; Shift the large one), and Enter places there; Escape or a tool change takes it away ("Use the arrow keys to activate the crosshair cursor. It will appear in the middle of the viewport indicating where the new object will be placed", Accessibility at Figma; #1839) |
-| Alt-drag duplicate | done | the copy snaps to the layer it came from too (edges, centres, equal spacing); Duplicate (Cmd+D) then repeats the copy's offset, also after a Duplicate whose copy was moved, as long as the copies stay selected (the documentation doesn't say; pinned from community answers) |

 | Drag threshold; double-click into groups and text | done | a press moves or resizes only once the pointer has travelled 3 px on screen, so a click or double-click made with an unsteady hand drags nothing; a double-click goes one level into a group and the next one edits the text under it, wherever on the text it lands, with all of it selected (a double-click in the text being edited selects the word) (`double_click_tests`); Enter on a selected text does the same (all of it selected, typing replaces it) and Escape leaves editing with the layer still selected (`text_enter_tests`) |
 | Scale tool (K): handles about an anchor, live factor, panel | done | Pressing K opens the Scale section with its factor field focused and its text selected; typing 2 (or 2x, 1.5) then Enter scales the selection by it 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), as one undo step, then closes the section and returns to Move with the selection kept; Escape in the field closes it, back to Move, nothing changed. Measured in Figma's web app, 2026-11-09. Tests: `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`. |

 | Date | Change | Summary |
 |---|---|---|
 | 2026-11-13 | patch | M1: Shift+Cmd/Ctrl+V (Paste over selection) puts the pasted layers just above the selected layer, in its parent and in the copied order, at its position; they went to the top of the parent's layers, so in an auto layout frame they ended the flow instead of following the selected layer. |
+| 2026-11-12 | patch | Drag modifiers compared in Figma's web app (2026-11-08): Shift locks a move to the dominant axis with no 45° snap, Alt copies, Shift keeps a resize's ratio (an edge scales about the opposite edge's middle), Alt keeps the centre, Shift+Alt does both, and a modifier changed mid-drag is read fresh on each move; FigCraft matches in all six, Ctrl/Cmd while dragging could not be measured; no code change | this page |
 | 2026-11-08 | patch | Smart guides: the object snap threshold is 4.5 screen pixels, measured against Figma (a dragged edge snapped at a gap of 4.4 screen px and not at 4.6, at 100% and at 200% zoom, Snap to pixel grid on); FigCraft used 5. Equal spacing shares the move's threshold so it follows; ruler-guide and rotation-origin snapping keep 5, unmeasured (`transform_behaviour_tests`) |
 | 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` |
 | 2026-11-12 | patch | M8: Tab while renaming the last layer in the Layers panel commits and opens the first row's rename, as measured in Figma's web app on 2026-11-12 (it ended the rename before); Shift+Tab on the first row is unchanged, not measured; Tab and Shift+Tab now move only the rename and leave the selection on the layer first renamed, as measured in Figma's web app on 2026-11-12 (it followed the rename before) (`tab_on_the_last_row_commits_and_wraps_to_the_first`, `tab_while_renaming_leaves_the_selection_on_the_first_layer`), Rename row |
