If I am not mistaken, I have noticed that the undo action doesn’t work. I have tried several times with different actions (layout elements or even deleted elements) and nothing happens when I click in the “Undo” action in the menu or press Cmd + Z. I don’t know if it is me doing something wrong.
The “undo history” is missing from some of the places but most of the basic steps are included into Undo. Does it happen also if you start empty project? I’m asking this because we were not able to probles from undoing actions on our test projects.
