Restoring previous versions of your file is very simple. In the Watch Tree (found
in the Main Window) just right-click on the good revision, choose restore, and
you are done.
Note that when you restore, no work is lost. As you can see from the image below, the version I
restored still exists, as does the one that was newer than the one we restored. Restoring a
previous version causes the file to be updated and a new revision to be created. You can restore
any version you want and suffer no loss of data.
