The problem that this feature will solve:
Quick undo/redo.
Brief description of the outcomes that you expect from this feature:
2 finger tap = undo
3 finger tap = redo
Add pencil pro hold press features.
What can’t you achieve without this feature?
Faster than clicking a button.
An undo gesture would be nice. Especially on the 13 inch. Maybe tied to a popup menu when squeezing the pencil or 3 finger tap /4 finger tap. Would worry about accidentally activating it all the time with 2 finger tap.
