In fact, I'd like these switches to be above the F-keys and to have tiny LEDs that glowed when the switch (not the device, just the power switch) was allowing power to reach the device. I still want indicators showing when the devices themselves are operating, but for security purposes, I would treat the power switch LED as a warning that the devices have power and, therefore, could be on whether they claimed to be or not.
