Can't undo "make detail" or "make structural" actions
When you select a brush and make it detail or structural (Brush -> Make detail ; Brush -> Make structural), you can't undo this action with a simple Ctrl+Z. You have to do the opposite action (if you turned a brush into a detail one, you have to select it and click on Brush -> Make structural).
Not sure if it's a bug or not, but it feels weird.
