I was on 3.3 for a bit. Had to update. Now I want to apply a negative offset to line data. It used to be easy to do this, I would just go to "format all" and click the stack icon. Now all that I see the ability to change all of their fill and outline color, outline width, and angle alignment.
Did it just get relocated? Did it ever exist? Am I crazy?
Well, I installed 3.3 on another computer and couldn't do it there either. That seems insane to me...
