From what I can tell the answer as for now is no, but is there any way to add custom menu items to the GUI that you could map to Linux commands or shell scripts?
It would be pretty neat if there was a way to provide an XML file of additional items to be included in the UI.
For example, if users have a home automation system and they put a script to integrate it on their Lakka system, they could add a menu item for ‘game mode’ that sets the lights etc.
