Give collections advanced / smart query capability

I am tech savvy and have no problem filtering my searches for movies by genre, sorting by rating, etc. The people that I am sharing my library with are not tech savvy. For these reasons, I’ve created several Collections - which are all tediously and manually created / maintained labors of love.

Then I discovered advanced / smart playlists and got excited about it. Some examples of playlists I created include the following:

Movies from each decade (1950s, 1960s, etc.)
Animated Movies playlist
Combined genre playlist (for example, combining THRILLER and HORROR)

What is GREAT about smart/advanced movie playlists is, unlike collections, they are automatically maintained as your library grows. I add a 1995 Thriller movie to my library, and it is automatically added to my 1990s playlist and my Thriller/Horror playlist. Wow! Cool!

Then I realized there is no easy button to share Movie playlists - bummer. So my friends have no way of benefiting.

My ask is the following:

Provide an advanced / smart query (similar to playlists) to create collections that maintain themselves when your video library grows. Boom! Very cool and functional feature - HIGH value to admins and their friends.

If you scroll a little ways into this → Collections | Plex Support there is a section in there on how to create smart collections. They function pretty much exactly how you are describing them. Including adjusting dynamically on the fly as the conditions of the collection are met by added media.

What Blkbyrd says… this feature already exists.
