I've got a bad habit of accidentally hitting the undo button, would a redo button be possible? Maybe longpress the undo button, though that seems a bit arcane so perhaps just stick it in the overflow menu?
That's a good idea. I'd see it as an option in a dialog, like when you tap and hold the pencil icon. Because it's an option that would only be used once in a while.
