Locked saved file
What about the ability to lock one or more of the save spaces of a session to make it so you can't overwrite it? I use every space in my session but sometimes i like to keep a particular spot saved in case i decide i want to roll back to a certain point. Like before i do the world engine. I usually remember to click on the second or third file in to overwrite so the one in the first position is much older than the rest. But this time i forgot and saved over it. If we could lock them out so that they cannot be overwritten, i would love that. Of course not a permanent lock. Just curious if anyone else would like a feature like that
