Yeah - I took that approach for a while too NeonKnight but when I'm working I like to do incremental saving so I'll rotate through version 1-4 when I do a save-as so I have different stages to roll back to. I'll give CC3 another whirl I think at some point but at the moment I'm working mostly in photoshop while I do the atlas view - I suspect CC3 will be more use when I break it down into regions.
