I made this one mostly for personal usage. After one year of using my device, the volume controls (the + - on the side) of my desire starts to stuck, and sometimes do not work at all. So when i listen to music on the device and want to change the volume i need to go to Home -> Settings .... and it really annoying as some song are louder then other, and i need to do this change often.
The program i created gives you only the option to change the Volume, that is it :) it also have an notification option so you can launch it from the notification bar.
