Came here to say the same thing: I want to access a previous version (or versions) of a shot list based on a previous draft of the script. For instance when a scene is dropped and then gets added back in.

Hi, this is extremely important: when working on a large project involving multiple people, make sure to create version control and regular backups of your project.

Yes. The ability to iterate a local backup would be very helpful. I want my AD to be able to have edit access, but I would like to backup just in case.

Yes, love to see this feature!
