For 2.2.0 update:

Firstly, thanks for album cover! But some little :) Please more big size... For example; upside full cover! Seek bar is so little, it must be a little bigger. The visualizer screen should have forward and back options! Not menu selection! It is very difficult to fast forward some musics, this so important! think its from codec. It is better to use the x button to close the track list. Thanks.
