It would be good to have a undo button and be able to restore a older version of your scenario. There's many times where I worked very hard then forgot to save and am able to see what I did in my history but I cant restore or undo. Once my computer updated while i was working and I lost all my progress.

BESTPRACTICE: Store your work on an ongoing basis. When you find out, that you need to use a previous version, open the list of previous versions and select the one, that you would like to use (see the screenshot).
