Gut aber braucht update

It is good app, but there are no must have things, like music visualization played from iPhone, no Multitasking, mic volume is too high and fills all the screen even with low settings, need some bar to regulate the sensivity, And no portrait mode.
I wanted to use it with a music dock station. It supports only portrait mode of course, and I wanted to play music from iPhone from the dock - also not possible!
