Shutdown using power button only

[DiffractionCircuit]

You already commented on the same request elsewhere:

Shutdown without touch screen

It would be nice to be able to turn off the QC without using the touch screen, perhaps by holding down the power button. It would be very useful for those, like me, who use a plexiglass case. I know that support says you can unplug the power cord directly, but it never seemed like a good solution to me.
