Default Improve Apollo Music Player

Hi Guys

I don't have the knowledge enough to modificate source code of Apollo Music Player, but I would like to improve it.
The feature that I miss the most is that I can't play just content of one folder.
I've already try to do something on Eclipse, but didn't works :/

There are some developers interested in implement this feature or help me to do?

The idea is create another tab (could be the last tab) and I select the folder to play, just like stock rom.

Thanks Wanderlei
