Just thinking out loud. Seems that implementing a vibrate/ring icon into the taskbar would be helpful. It would show a vibrate icon when the switch is on vibrate or a ring one when its on ring. I know i just have to flip the switch to find out, but I find myself flipping the switch back and fourth a good bit just to see if the red dot means vibrate or ring. Seems this would be relatively easy to put into the taskbar notifier program that's out there (which I love by the way).

Just a thought.
