@verius Dunno if I like that idea because long-presses can be really fussy on some devices.  My housemates HTC has longpresses like a fraction of a microsecond longer than normal presses so if you have anything on longpresses in an app on that platform it makes the app a real nightmare for her.  I think a swipe might be a better idea unless you plan on putting a lot of stuff in there.  Can always have a "..." or "More" option for the less common functions.
