Undo and Redo Gestures

[PeterQueen]

Hi,
I'm really enjoying the app so far and I think it would be really great if gestures for undoing and redoing actions could be implemented. Apps like Procreate, Notability and Goodnotes use these types of gestures: two-finger tap for undo, three-finger tap for redo.
I know that there are the specific buttons on the toolbar but the gestures would really speed up the workflow in my opinion.
