Holy Balls! File Recovery is awesome!!! Especially when you're a geek like me and you start playing with high res 3D projections without saving on a piece that doesn't really need it:
Seriously, I started up a dumb 3D layer when I was working with the chains, pressed a few too many buttons too fast and I crashed PS (first time in a week and a half btw). After 20 minutes of agony (did I mention I hadn't saved in a while) I finally decided to take my lumps and force quit the program. I bring the thing back up and what do I see? The work file, exactly the way that I left it!
I am staggered at the number of hours of work that I would have saved the last 10 years if I'd had this feature. Literally staggered.
