If nobody has done the work for you already, just write your own. It is easy and you can then upload the remote.conf you create to the remote.conf repository and help others that might have the same problem
To get to the .config folder am I right in thinking in Kodi (LibreELEC) File Manager I choose:-
1. Add a source> browse> Root filesystem> Storage
2. Then select my added source (storage) and the .config folder I need to add my remote.conf is there?
I have added a remote.conf file to the above .config folder and it made no difference (maybe it was the wrong one), I did restart Kodi
I noticed that there was already a remote.conf file in the LibreELEC root directory, should I have deleted this one, or does a remote.conf in the .config folder supercede the remote.conf in the LibreELEC root on loading?
