I’ve noticed that too, but I didn’t think to mention it. Yeah, the “Collections this movie is in” recommendation only displays one of the collection’s contents below the metadata. It’d be nice to see all of them.
While we’re at it, can we make that “Collections this movie is in” a clickable link taking me to that collection? I’m disappointed that I cannot get a larger perspective of the contents of the collection without navigating to it the standard way. Dynamic navigation around my library through “related movie” or other cues like that is a fun hobby of mine.
I would also like to see collections that share the same name across libraries being merged – in the screenshot above it shows the “italian history” collection from my English library, then the “italian history” collection from my French library (aka. feature request: allow a single collection or smart collection to go across playlists).
