No Landscape Mode...REALLY?!!

Havent seen bush league coding like this since Commodore 64 days!
Im disabled and My iPad is fixed and mounted in landscape mode but this apps interface is ONLY PORTRAIT mode unless your playing a video THEN it will allow landscape viewing. Have to wrench my neck and head sideways just to choose what I want to watch then and only then can I sit up. Total BS!
