How to filter intersection of tags/collection

[bitmap]

Well, yes. Not necessarily how you'd want, however. If you filter by multiple tags that creates an aggregated list of all media that match ANY of the tag criteria you've selected. But you can use AND logic with multiple criteria from different categories: any combination of Filters, Status, Features, Genres, Parental Ratings, Tags, and Years. Note that this means ONE criterion from a category and ONE criterion from another category.

So I could do...

Filters: Unplayed
Genres: Science Fiction
Tags: dual-audio (custom tag)

You should be able to edit things like genre and tags in the metadata manager, but it would likely be tedious if your library is large.
