simple but useful: volume control
 

If any of you have used a media software to play songs - which most of you have - you'll notice the volume control, so you can turn down or up how loud the songs are played. I've recently noticed Limewire Media Player doesnt play as loud as windows media player. I have to play songs in WMP in order to have it loud enough for me to hear across the house, it'd be cool if I could save some CPU by have limewire play it, as loud as I need it.
