 ## Progress log
 
+- **2026-11-05** · M4, #1830: a paragraph's base direction can be forced (Text ▸ Text direction: Auto, Left to right, Right to left) as Add right-to-left text says ("controls are available to override text direction per paragraph"). `ParaList::direction`, `text.direction {direction, ids?}` and the three menu commands (the edited paragraphs while editing, else the layer's), `node.set textDirection`, the Type settings control once a right-to-left script is in the text, `textDirection` / `lineDirections` in inspect, the CSS `direction`, and the `.fig` lines' `sourceDirectionality` in and out. Layout gives each paragraph its base level (`Bidi::of` per paragraph). Tests: `text_behaviour_tests::text_direction_is_forced_per_paragraph`, `fig::text_direction_tests`.
 - **2026-11-05** · M1, #2003: the Design panel's Boolean groups menu leads Union, Subtract, Intersect and Exclude with original icons drawn in code from rectangles and polygons (two offset squares, the result filled at reduced alpha); each entry still runs its command.
 - **2026-10-30**: M8, #1125: damaged `trak` size-table offsets are checked instead of wrapping on 32-bit targets, and an incomplete normal track is dropped entirely, never returned in part. Font indexing makes its existing bounds explicit, preserving later faces and sparse name-table reads. Synthetic regression tests in `fontdb_tests.rs`. Numbers unchanged.
 - **2026-10-30** · Text style dedupe is O(spans) (M8, #1102): `shape_text` deduped spans into styles by a scan over the styles already collected — O(spans × styles), so a styled text's dedupe grew with the square of its runs (a synthetic 50k-run text with 100 alternating styles spent 7.7 ms in it). Now the last two styles again (spans run in blocks), then buckets keyed by a cheap fingerprint (family and style bytes, size bits with −0.0 folded, the enums, fill count and solid colours), each bucket resolved with the full equality: the result is the scan's, never worse than it, and O(spans) when names and sizes differ (the same synthetic text: 2.6 ms). The font-db write lock is untouched: `find()` loads faces, which needs the write. `layout_dedupe_tests`. Numbers unchanged.

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.

 | Eyedropper (I) | done | picks the colour seen under the pointer (opaque) into the selection's fill and the recent colours, one undo step (`fx_behaviour_tests`); with Cmd/Ctrl+Shift held it makes a colour style or variable of it instead, as the reference app's eyedropper does: a Create from color window asks which, its name (the next free "Color n") and a variable's collection (the file's first, or a new one made with it in the same undo step), and leaves the selection's fills alone (`eyedropper_create_tests`, `sampled_color_tests`) |

+| 2026-11-05 | minor | M4, #1830: a paragraph's base direction can be forced (`TextDirection`: Auto, Ltr, Rtl on `ParaList`): Text ▸ Text direction ▸ Auto / Left to right / Right to left (`text.directionAuto` / `Ltr` / `Rtl`) and `text.direction {direction, ids?}` set the edited paragraphs while editing, else the layer's; `node.set textDirection`; the Type settings control once a right-to-left script is in the text; inspect `textDirection` / `lineDirections`; CSS `direction`; `.fig` lines' `sourceDirectionality` in and out. Layout gives each paragraph its base level (`Bidi::of` runs the algorithm per paragraph, as it starts over at each). Before, direction came from the letters only ("controls are available to override text direction per paragraph", Add right-to-left text). Tests: `text_behaviour_tests::text_direction_is_forced_per_paragraph`, `fig::text_direction_tests::a_lines_source_directionality_is_its_paragraphs_direction_both_ways`. |
 | 2026-11-05 | patch | M1, #2003: the Design panel's boolean operation menu leads Union, Subtract, Intersect and Exclude with original icons drawn in code (two offset squares, the result filled at reduced alpha). Numbers unchanged. |
 | 2026-11-04 | patch | M1, #1852: a press on one of the open gradient's handles or stops on the canvas is the colour picker's own, not a press outside it (Figma keeps the picker and the handles up while a handle or stop is dragged; the stops are made to be dragged: "You can click and drag a stop to change its placement on the gradient", Use gradients as a fill or stroke). The canvas took the press and began the drag, then the picker, drawn later in the same frame, saw a press outside its card and closed, committing the drag's interaction at once; the handles vanished with it and the drag went on without an undo step of its own. Now the picker stays while a gradient handle or stop drags, and the drag is one undo step; a press elsewhere on the canvas still closes it. A handle drag whose button goes up off the canvas (over a panel or the picker) ends there too, instead of waiting, uncommitted, to move the handle to the next press on the canvas. Tests: `colorpicker_selection_tests::dragging_a_gradient_handle_on_the_canvas_keeps_the_picker_open`, `colorpicker_selection_tests::a_gradient_drag_released_off_the_canvas_ends_there`. |
 | 2026-11-02 | patch | M8, #1875: a click with the Bend tool on a sharp point between two segments gives it handles along the line between its neighbours, a third of the way to each ("Click on a point or path where you want to add a curve", Edit vector layers); a click on a curved point still makes it sharp, a drag still sets the handles by hand, an endpoint is left alone. Between a handle's end and a point both within reach of the pointer, the nearer one on the page is hit (the handle on a tie), so a short path's point (its handles a few pixels long) can be clicked again. Before, only a drag curved a point, and a short one left two tiny handles in its direction. Tests: `vectoredit::tests::short_handles_leave_their_point_clickable`, `vectoredit::tests::a_bend_click_curves_a_sharp_point_between_its_neighbours`, `bend_tool_smooths_and_sharpens_points`. Numbers unchanged. |
