1. Support multi-tasking/background play (like every other app).
2. Auto rotate (like every other app).
3. Complete reconfiguration of menus/remote. The entire config looks like an afterthought and is a serious step back from what was on my Win phone years ago. Remember this is a MOBILE app - simplify, simplify and please revove the all the unwanted, unused and otherwise unoperable buttons.
4. Audio only.
Very disapointed in what is one of the highest priced apps out there. Especially when you consider that I bought it once several years ago for Win phone and then again when I moved to Android in 2010.
