I was texting a ton last night, landscape of course, and when going from the Messages application to another (which also utilized the landscape feature), the home screen was obviously still portriat. I would love the option to landscape the home screen. Nothing crazy, but when turned, the icons and labels just simply do an about-face and swivel to be read in landscape. Nothing would move, the dock would stay on one of the sides (depending on what way you turned it, obviously). I can't do a mock-up, but I hope I'm making my idea clear. Not a big deal, but would be a nice little feature to keep everything consistent while switching apps, if you happen to be in landscape.
