screen brightness control So far most of my use (loading files, testing apps, etc.) is done with the USB powering/charging the device, I have set the screen to "never" dimming. What would be a simple way to switch to a more usual system when not connected to power, hopefully without too many levels of selections? Presently I go to "all programs>settings>power management>display time out" and then cursor to some time that is bearable ("5 seconds" is too annoying, "never" uses too much battery). Love.
