I used one of the first versions of pierogi, it worked quite well in portrait mode. Recently I installed the latest one, and whole UI in this orientation is a mess (button icons/tabs, panel selection etc). pierogi greatly expanded its functionality but portrait UI was left behind.
But, given specific nature of pierogi (which is effect of N900 IR diode placement), I don`t think that more time investment on coding the portrait mode is rational any more - quite opposite.
If to actually use pierogi one must hold phone in landscape orientation, lock (hard code) pierogi in landscape orientation and drop portrait support completely - because You can`t use it effectively in that mode anyway. Simple as that.
From my experience, it`s a case with many (all?) "remote control" apps out there - orientation is imposed by construction (diode placement) of the phone.
