Sorry for the wait - My AVR was broken and had to be fixed by Pioneer before I could start retesting the app.
I cleaned up major flaws and inconveniences and now the app should work much better.
I'm thinking of redesigning some parts of the "basic" screen.
What functions do you use most when controlling the AVR?
I think the SOURCE and the VOLUME are the most important ones. What do YOU think? please add a comment below :)
