Improve the functionality of the Deezer component of the app, so that it resembles more closely the Deezer app itself. For example, why is it not possible to sort albums and artists in "my Library" alphabetically?
The option to exclude Audio books in my iTunes library in the syncing by the Soundtouch app. I want to be able to select random play of my entire library without having to hear a chapter of some book thrown into the mix. Surely it would not be very difficult to implement a tick box for that?
It would really be a fantastic add-on if a future "series" included a button on the unit to enable "play anywhere" that would engage all other units on the same network so you wouldn't have to use the app. (If possible)
