I want an undo command besides the keyboard and faster than edit>undo . maybe an on screen button would work. I use the surface pro 4 and would like the pen button to undo, but windows cannot reprogram it to control Z. which is more of a microsoft/windows issue. but if I could add undo to the tool bar, and something, that would make a difference. Another solution is to make the touch work space more useable.
