Well, IIRC we originally had tags inside TMM, so this might be some left-overs...
And we never got a good idea, how to present those 400 tags to the user to let them choose... or to filter them...
But always open for improvement ideas


Well, there are no NFO updates.
When already imported to Kodi, Kodi does not reread any new values (except you know how to force this)
TMM works kinda same way. Once the movie is in our database, we wont read it again.
(But we might preserve unknown changes while writing it)
This is always a chicken-egg problem, what side of this information is more accurat, aka the master.

Kodi does even not write this information back to NFO.
You have to export the (imho) complete database, to write those new values.
Then in return, you could delete one/all movies out of TMM database, and reload them...

Usually, once a movie has been polished by TMM, and imported into Kodi, you barely touch it on either side.
But yes, for "backup" those values, this would be nice to store such information back in NFO...


Other way would be, to use external services like trakt.tv....
