Hi, I have a (small) request : i would like to see a second library for example I have 2 movies (the same movies) but one is in English and one in French, with the actual multi media library I can’t know which one is which language. It would be great if There is a library per source, I have an nfs source " en-movie" and I library with only movies from this source and an other source “fr-movies” with an other library which have only film in French but there are not mixing together. (Or a filter by language)
This would be dependent on Kodi function. Have a look here.
You could use the profiles feature for this
