Undoing and Redoing Document Changes
You can undo or redo single actions (using the Undo and Redo commands). However, gobeProductive allows you to go much further, by using a History panel that displays all of the changes made to a document. Using this panel, you can re-trace your steps and actions.
You can move back and forth within the document history. In this way, you can back out a number of changes, or return to the point where you made a change to remind yourself of your previous actions.
