Undo Button for All Project Functions

Similar to the recycle bin idea but more of a real time snap back to your last action. I know there is some functionality for this but our PM's accidentally delete tasks accidentally because they are moving so fast and it would be great if there was a button similar to other products out there so you can undo / redo your last several actions within a project. Having to go to a recycle bin to restore work is a multi step process that would cause frustration in times of fire drills.
