Maybe it's just me, but I think the 5 issue cut-off should be a loose guideline, not hard and fast. There's already some looseness in that we have zero-book categories just to show we can't take certain titles. And some high profile books might deserve their own sections, even if they are short runs.
I'm thinking here of the Ajax Phantom Lady as something I think probably deserves its own folder, as an example. It's probably the highest profile Ajax book; and since it's the drawing card image we have for the publisher we should probably have it flagged once you go to the subfolder. That's just my thinking, though: What do others think?
Oh, and the bigger upload window is NICE to have!
