Precision annotation without leaving the canvas
The editor exposes far more than four markup buttons. It behaves like a real review surface with layers, keyboard control, and reusable annotation state.
- Arrows, lines, rectangles, circles, text labels, highlights, blur regions, step markers, freehand paths, spotlights, magnify lenses, and ruler overlays.
- Stroke style, fill, opacity, font size, magnify zoom, duplicate, keyboard nudge, select, hide, reorder thinking through the layers panel.
- Undo and redo for annotation history, separate beautify undo stack for layout and styling changes.
