8 tools: brush (smooth), marker (rough edge), eraser, line, rectangle (filled/outline), ellipse (filled/outline), arrow, and paint bucket fill.

What is HiDPI support?

HiDPI/Retina screens have more pixels than standard displays. The canvas renders at double resolution and scales down, resulting in sharper lines.

How does undo/redo work?

Every stroke is saved as a separate action in history. You can undo up to 40 times and redo up to 40 times, or press Z/Ctrl+Z.

What keyboard shortcuts are available?

B=brush, M=marker, E=eraser, L=line, R=rectangle, O=ellipse, A=arrow, F=fill, Delete=clear, Ctrl+Z=undo, Ctrl+Y=redo.

Is my drawing sent to a server?

No. All drawing is done locally on HTML5 Canvas. Your doodles are never uploaded.
