Proswitcher should be available soon, sounds like what you are looking for.
I would love to be able to run two apps on the screen at one time, side by side. Would be great for when waiting on say a YouTube video...you could do something else and still monitor it's progress. Backgrounder allows you to keep loading the video, which is freaking fantastic since that was so annoying that you had to sit there and wait for it, but you still have to keep checking back on it.
Better Camera Kit support. You know....Import/Export. Support for mp3/wav/anyfile transfer through cam kit. Support for Portable USB Audio and Midi interfaces such as the M-Audio Transit and M-audio UNO USB-Midi Adapter.
I'd like multiple desktops, and one where i can spread all my absolute favorite porn clips all around and sorta pan through them with little apple bookmarks at my favorite bits. I would also like a screen that is self-cleaning, and fingerprint recognition so my uh, fun isn't ruined.
