I think it would be nice if there was a way to gracefully shutdown the PC from within Big Box.  I don't know if that would be a key combo or, a menu item.  This is a conundrum for me.  I went with LaunchBox / BigBox because I wanted a wow factor for the cabinet I'm giving to my kids on Christmas.  BigBox just feels awesome in a way that RetroPie is not.  But having chosen PC over a Raspberry Pi well, there seems to be some consequences related to features on the cabinet itself. Like, I can wire into an RPi to control power and volume.  I think that the PC needs to do it in software, instead.  So, can it be done from the BigBox menu, possibly?  Or, a platform hack?
