- Freeform drawing tool: new sidebar button enters a click-to-draw mode
that appends points, shows a live ghost preview line, and exits via
Enter or double-click (near the start point closes the path). Works
end-to-end through all four render pipelines.
- Polygon authoring gestures: double-click on a path inserts a vertex on
the nearest edge; double-click on an open polygon's endpoint resumes
the drawing session from that end, reversing point order when needed.
- Stroke + closed-path properties: all shape types (rect, circle, text,
polygon) expose stroke color, stroke width, and (for polygons) a
closed toggle. Fill and stroke each support a "transparent" switch so
shapes can render as outline-only or fill-only.
- Mask preview no longer inherits the user's stroke — the dashed ghost
keeps its own outline regardless of stroke-width changes.
- Playhead no longer dims on inactive timeline tracks; only keyframes,
segments and clip blocks fade.
- Properties panel point-count control for polygons, plus per-keyframe
points animation that correctly interpolates once a baseline exists.
- Pivot drag hides the rotation handle until release.
- Transformer attach retries on a short timer to avoid races where the
Konva node hasn't mounted yet when selection changes.
