I have all of my video content in one main root folder, which Plex is connected to. However, there are certain shows/movies that I’d like to group independently. I still want my content in the same folder structure behind plex, but I think it would be useful to group them into “kids shows” or “parents shows” instead of just by library so that when users are in the app, they can quickly toggle between different show groups.
There are collections now.
