I have one suggestion for a future release (which I know may be a while since the developer is going to be busy with other things for a bit)

In the Power Management options, is it possible to get a confirmation warning. I'm always worried when I switch to Offline Mode, that I'm going to accidentally hit reboot. Offiline mode can probably be left as it is, but for reboot and shut down a Confirm/Cancel prompt would be nice.

I haven't actually ever hit it, but I know if I ever let someone play around with my tablet, someone is going to click on one of those.
