Undo/Redo hotkey has been removed recently.
I'm really frustrated.

Can you re-add Cmd-Z/Cmd-Shift-Z hotkey?

It's definitely mandatory hotkey for keyboard users, and it's the most frequently used hotkey. with the pencil on my right hand, and with Cmd-Z hotkey on my left hand, it was a perfect way to draw and erase something almost at the same time.

if not, I have to click "undo" icon.
That's very inconvenient for ipad-keyboard users. Pls... ㅠ.ㅠ
