Some ideas I got, after playing around for some hours with your great soft:
1) direct access to some functions (fastforward,rewind,nexttrack,volume etc.) via keyboard keys. I would need this for my girder and my remotecontroll
2) fullscreen-option for GPS software. Travelbook and Navigon (the most favourite over here in germany afaik) both can only be used fullscreen.
3) gapless playback! Just listened to a mixtape and there was a pause between each track. Maybe also some fading while skipping.
4) clickable progressbar for the the running song
5) simple menu to start external apps (embedded or fullscreen)
6) Sometimes when i fast-forward the song hangs and i have to pause/play or ff/rewind again...
And one more time a big thank you for this great soft!
