   Align to Artboard uses the active artboard, the one the Artboards panel highlights (`object.align {artboard}`). A press with a selection tool inside an artboard makes that artboard active; with the Selection tool, a Shift-click on an empty spot inside an artboard makes it active and keeps the selection. One selected object is aligned to the active artboard too, whatever Align To says (a lone object is never the key object). When an action plays, its Align to Artboard, All on Active Artboard, Paste in Place, Paste in Front and Paste in Back steps that name no artboard use the artboard that is active then.
   Choosing the Artboard tool (Shift+O, its toolbar button, Edit Artboards in Properties or Document Setup, or the Artboards panel menu's Artboard Options…) starts it on the active artboard: the canvas outlines that artboard, and Delete, Cut, Copy, the Transform panel and Artboard Options act on it.

Object › Path › Remove Anchor Points (`path.removeAnchors`) removes the direct-selected anchors without opening their paths (the Delete key still deletes them with their segments): the neighbours keep their handle directions and their facing handles are refitted so one cubic follows the two old segments, and straight sides stay straight. The Delete Anchor Point tool uses the same refit. The Control bar, the contextual task bar, the Properties quick actions and the canvas context menu offer it when anchors are selected. With anchors selected, the Control bar and the Properties panel also convert them to corner or smooth (`path.convertAnchors`), connect end points (Join) and cut the path at them (`path.cutAtAnchors`, also on the task bar and the context menu): a closed path opens there and an open one becomes one path per piece, each cut leaving one of its two coincident anchors selected so a drag pulls the path apart.

   - Divide uses open lines, bent paths and curves as cutting edges (#1307), preserving the frontmost filled face's appearance and holes. Engine tests cover implicit closure of filled open contours and unrelated objects; native automation confirms independent piece movement, one Undo/Redo, canvas/window captures and an exact saved-document read by a separate CLI process. The shared planar map retains its 4,096-segment cap and filled-area fallback; other Pathfinder operations are unchanged.
   - Initial live Revolve (#605, #846): a portable geometry and shading crate (`three-d`), editable path and compound profiles, compact options with artboard rotation and light gizmos, SVG/PDF vector output and Expand Appearance that can trim covered faces. Open ends are uncapped, shading is flat with one light, and intersecting surfaces' visibility is approximate ([revolve.md](revolve.md)).
   - Live effects with previewing dialogs: Distort & Transform, Path, Convert to Shape, 15 Warp styles, Round Corners, Scribble, Effect → Pathfinder (all 10 operations, live on groups; several loose objects are grouped first, in one undo step), Color Adjustments (Brightness/Contrast, Curves, Levels, Hue/Saturation, Shift to Color, Temperature/Tint, on vectors, live type and embedded images), and raster drop shadow, glows and feather.
