Found Footage: iTunes-based App management concept
Apparently I'm not alone, because this video by svdomer9 shows a nice mockup of how such an iTunes-based app management scheme might work. I really like the idea in general, though I would suggest that there also ought to be a kind of well at the bottom which would hold the applications until they've been assigned to a specific page. Naturally, it would be nice to see a bit more sophistication on the iPhone side as well so that it would be easy to go directly to a given screen (via the roller interface, perhaps) as well as directly send Apps to a given page (e.g. a pop-up menu that would appear when you hold your finger on an App for a few seconds).
Whatever the particulars, it seems that we need something like this on the iPhone going forward. If you had Apple's ear, how would you do it?
