Just got Plasma 5 installed and running well, and there's a couple things missing, 1 I can probably cope with (easy audio device switching), but the one I really am at a loss with is the missing shutdown/reboot buttons. I thought I'd just have to be in the operator group, but I guess not? I'm new to this sort of stuff here (first FreeBSD desktop)...how can I enable users to do shutdown/reboot operations?
