Add rotation for selection boxes as well as single-object selection (as in for individual strokes and figures)
For rotation, I was thinking a little handle on the outside of the selection box that would allow for a change in angle of the selected object.
As well, a mode for selecting single objects such as selection on stroke for moving (maybe resizing too if possible) would be extremely useful.
Being able to select, move, and resize things is what makes using this app so much better than paper! I'd love it if these features were added or improved upon.
