Simple question: how do you disable all keyboards in Kodi? I tried looking for the keymaps folder so I can edit the keyboards.xml file but can't seem to find it. If there is a way to master lock (using a PIN) the video player before someone can use the media controls, that would be even better.
If you don't want a keyboard, you could simply unbind all the keyboard commands. In order to do this, you need this addon:
While this might not be the most elegant way to do this, I think it would work.
