Idea from a student: add an undo/redo stack.

I think animating an undo would be a lot, but just saving the tree (and other state like the mode) at each stage and enabling jumping to it would be pretty easy.

Related, undo could cancel whatever operation/animation is currently happening, and then restore the state to just before the operation started. This would be nice for annoying long animations that weren't intended (e.g. switching modes).
