When organising movies into collections, it’s frustrating that you can’t see which movies are already in the collection, without hitting the edit button and switching to the “Tags” tab.
The best thing for this would be a batch-editing UI, but adding a “Collections” column to the list view would be a (presumably) technically much easier change, that would also help.
Just an update here - turns out there is batch editing! I had assumed the circles in the top left of covers in the Plex app were to toggle watched/unwatched status (which was shown as circles in Plex Home Theater), but I discovered they are actually checkboxes. You can also check a range of items by checking the first one, holding shift, then checking the last one. And can then edit the collections of the whole batch.
