Just sticking to per page. I have coded being able to name individual saves but I have doubts over it's stability. It seems to work -almost- all of the time but on a few occasions it just freaks out and I'll be damned if I know why. Plus it starts to get a chore to have to type save files after a while if you get a load of branching options close together.
So given you name the page whatever you want "Huity's bastard path 47", "Temp saves for Plant scene" i'm happy to just stick to what is there. Given that most of us weren't aware of it in the first instance it's better than nothing - and doesn't crash
