Undo or versioning functionality in pages editing

[spiazzi]

I think is important add undo functionality or versioning in pages editing.
The drag and drop sometime is not precise and sometime it is unpleasant.

I accidentally delete things all the time and am fearful of accidentally doing something I don't want and not noticing. Improvements could be:

• undo
• versioning (so i can just revert to last commit)
• "are you sure" when deleting something

Just a heads-up: In the right-click menu in the pages editor there is a new option "Select element" which lets you select an element and right-click another element and move/clone the selected element to that position.
This take some of the inaccuracy out of moving elements in the tree. This is quite a step away from full "undo" functionality but it should help a bit in that area
