On/Off button

Kore allows to Power, Quit, Suspend, Reboot, Shutdown using the power button. I find this a bit confusing. I have setup a mediacenter, enabled WOL and setup kodi as a starting program. Therefore, I am mainly interested by Power and Shutdown actions (depending if Kore is able to communicate with Kodi or not).

For the time being, my major issue is when I select by mistake the “Quit” option, I will not be able to control anymore Kodi using the Kore app. I have to restart manually Kodi by another way before having back the control from the Kore app.

I would like to know if that is feasible (and a good idea) to enable/disable on demand the 5 options from the configuration menu? After for me, I would be easier to have a simple on/off button but it is not maybe the case for everybody.
