It would be extremely helpful if there was an easy to use versioning snapshot feature. Meaning, before I make a change to a Piston I can click on one button to take a point in time snapshot and add a comment to the snapshot. Then with another button I could easily roll back to any previous snapshot if I didn’t like my new changes. Just like a virtual machine, if you are familiar with that concept.
I know you can do backups or clone a Piston, but that requires more steps than just a ‘one click’ snapshot and restore. Plus you can’t easily add a description to the snapshot like “working 8/21/2017” or whatever. I’d like to experiment with several Pistons and this would make it much easier.
