How it works
Flip, rotate, undo
The buttons beside the drawing tools: turning what you have already made, and taking it back.
Flip left to right
Turns the whole design over. Not the same as mirroring: mirroring doubles each stroke as you draw, this reverses what is already there.
Useful late, when a face is looking the wrong way out of the frame.

Flip top to bottom
The same, over the other axis. Between the two of them any orientation is two clicks away.

Rotate
A quarter turn each press, so four presses come back where you started. The canvas swaps width for height with it, which matters when a board or a hoop is not square.

Undo and redo
Back as far as you need, and forward again. A whole drag counts as one step, so a wobbly line costs a single undo rather than forty.
Ctrl+Z and Ctrl+Shift+Z, as everywhere else. This is permission to experiment — you cannot ruin anything.
