I've tried Pandahome, LauncherPro and Zeam (downloaded from the market). I settled on Zeam since it seems to get back to a vertical orientation better (there's a setting under preferences/general for sensor rotation) and the wifionoff widget seems to work better than on LauncherPro. It may be all my imagination but thought I'd share since I've benefited so much from other people's work on the novel.
