Per-folder/share/library metadata language

It would be great if I could do a language setting per library to control which meta data to pull.

I typically organize my collection by a few folders, Swedish (native), Foreign with subtitles and Foreign.
I would like to have Swedish metadata for my Swedish collection and English for Foreign collections.

By setting a language indicator to each library you could easily control this, no language selected would g for default language.

And please keep the genres by the default languages…
