This looks perhaps like an add-on request, but anyway.

Given some people prefer the original audio, other the dubbed version; some have problems with English, etc., I would consider it very handy if it was possible to

1. in some setting, select, say, up to 5 “important” languages — the following steps can't reasonably be done for all possible languages, it would cluuter the GUI terribly
   
2. now, whenever a movie is scanned, Kodi would determine which audio and subtitle tracks it contains
   
3. if an audio/subtitle track in any of the “important” languages was found, the movie would be tagged accordingly. The tags would be displayed in a similar way as the current tags showing the video/audio quality, so that one at the first look sees which audio and subtitle languages (of the “important“ set) the movie contains
   
4. and, it would be possible to filter movies based on the tags, e.g., — presumed both Czech and English were set as “important“ — to display only movies which contain an English audio and Czech subtitles
   
5. of course, the tags must be editable (in case the movie does not contain language tags, or the tags are wrong)
