The UI needs a lot of work, but other than that this baby packs a ways more features than I've ever seen in any calculator.

The orientation does not seem so bad in portrait mode except when you select the option to view more "function options".

I know nothing about qmaemo5rotator, srry....Hell, I'm yet to even learn about qt although I am a c++ fanatic.

Looking forward to future improvements! always nice to have a good scientific calculator, especially when it's super powerful.
