How do I undo an accidental stroke? I cannot find undo functionality anywhere In the app, am I blind?
Use two-finger swipe to the left to undo and a two-finger swipe to the right to redo.
Use three-finger long press to bring up the history slider. Then, with those same three fingers, pan left or right to run through the history of the sketch.
Hope that helps,
Thats it, thanks!
Maybe add a way to replay the first time user tutorial, it was probably shown there when installing the app.
