The Ability to Reboot the Host over Parsec would be very nice.
here is a work-around for you assuming host is running windows; create a new shortcut on your desktop, start menu or other location with the target:
shutdown /r /t 1
You could bind this to a hotkey if you wanted to even.
This is super old, but you can do this if you reset host on Parsec or if you restart and you're running the parsec service i believe
