Yeah it is annoying. It would be nice if there was a universal "swipe" like you said, that would change from portrait to landscape and vice versa. Then it would either work or not work in certain apps depending on if they support landscaper or not. Maybe even a popup could tell you that landscape isnt supported in this app (kinda like the "nothing to undo" popup).
