How do I see what custom markers are assigned to a movie? Or is filtering by custom markers the only way? What about tags? There doesn't seem to be a way to check the tags at all, other than viewing the .nfo file.

I'm planning to use custom markers and tags to help identify movies with extras and commentary tracks.

Custom marked movies has another color that can be set in Settings => Movies => General => Custom Marker. Custom markers are an "Ember only" thing.
ATM tags are only visible in the NFO. I will try to change that in one of the next releases (maybe as list in the info view on the right side).
