Just after Black Inc came out I asked for a mode that automatically trashes completed puzzles and keeps my desktop tidy. I've been thinking this over and now I want a pony, too. Instead of puzzles being individual documents that I have to manage, I'd rather have the puzzles from a source (or maybe sources) be a stream of done/undone items. Like iTunes working with podcasts, it should refresh periodically / when opened / on request. Then when I want to do a puzzle I can just hit the newest or oldest undone puzzle in the stream. I'm thinking this could be very much like iTunes and the way it tracks listened / unlistened podcasts.
