As a project manager, the need to reverse an action is vital. Especially if we expand a summary task to see the down flow effect upon a project. If I have a summary task end date scheduled, but don't take notice, and move it forward to project impact, I don't want to not know the previous date.
I've also noticed an "undo" popup at the bottom of the browser. This doesn't appear all the time and once it "times out" you can initiate it again. The popup should have an manual closeout because I need to think about what just occurred. The time out is way too fast.
Finally, a snapshot or previous versions revert option is needed, especially if new to the tool. I handed over a project to someone else, that was learning the tool and accidentally changed things and did not know how to start over!
