Please read folliwing notes if you want to create custom skin.

Limitations:
----------------
1. You must not rename or remove named (with specified "name" property) controls 
2. You must not create the custom named controls
3. You must not move named controls to other activities (windows)
   For Example: you can move all controls from playlist screen to main screen, 
   but you cannot move all controls from equalizer screen to main screen, 
   because equalizer is located in separate activity (window)
