Take care of the sense, and the sounds will take care of themselves.
Due to chronic lack of time, I decided to publish full source code of Vista Battery Saver on CodePlex. I believe, that only this way, I can assure this really useful and important software to live. All developers, what to take care together with me on this soft development are welcome to join this project.
Good luck and thank you. Vista Battery Saver @ CodePlex
