I am back from my holidays and have just finished responding to all my emails 
The next feature I will add is the generating of playlists when syncing music. This has been asked for by a few people and would be very useful. Look out for an update in a week or 2!

Keep up the good work! Would like an option in the app to enable syncing non-wifi. My 4g upload speed is actually significantly faster than my wifi
