First of all, i must give thanks to all the developers who have contribute this awesome player. The whole thing is neat and works effectively.
Improvements:
- automatically add the *.cue to the playlist whenever i click on them (correlated to *.ape/*.flac)
- Add various locations in hardrive cus now i can only bound to one location with its sub-directories
- some highlights in both drawers and playlists that can make the categories look more distinguishable
- the ability to view covers and backcovers
lastly, i'm not sure what exactly i want here,
but i find that when i have a large amount of songs, i find it difficult to play what i wanna play,
maybe a filter will do, or tree style playlist , or some kinds of smart playlist ...
I don't have much times to read through all the posts here, maybe some kind of ideas are already duplicated. whatever it's 
thanks for the release and keep up the hard work!
