Say you started working on something last week, and the last time you saved it was two days ago. Lisa keeps track of all of the changes you made since the last time you saved, so every time you set aside your document, it updates it without even asking.īut say you screwed something up in your document? You can simply tell Lisa to revert to the previous version! In fact, the only reason you would ever want to save anything on Lisa is so you can revert to the previous version later on. If you do tell it to save something, it makes a reference file that you can revert to at a later time. Another nice thing is that you never have to tell Lisa to save something.
