Touch Workspace Eraser
Drawing in the touch workspace is not usable without an eraser. A Simple undo is not enough. Try to undo something you drew 5 minutes ago without undoing the stuff you like and you'll see what I mean.
This feature being absent is such a blatant oversight. How can an illustration program not support erasing. I will stop using all my Adobe programs and find alternatives since clearly 2 years wasn’t long enough. How this feature was released without eraser or layer support is incredibly embarrassing.
I'm stopping using illustrator purely for lack of this feature
