I typically have half a dozen large studio session files open (from the same session), and if exit out or switch sessions, when I go back and just want to open one file, I have to wait while all the previous files reopen. It takes minutes to load each one, and is a total drag on productivity. I only want to open them on demand. If I exit the session, let 'em close! Next time I am in session, its because I need to access a particular file, not all of them!
