This is a simple mod which was quite useful for lazy people like me. It basically pauses your GTA V (offline) save progress allowing you to experiment with customisations.
Great for messing up missions without ruining your stats and all.
...wait, correct me if I'm wrong, but can't you simply disable auto-save in the game menu, and save to an empty slot when you're ready to test? Then if it fails, just delete/overwrite the game save?
