I have multiple lists of films, and when viewing one list, I’d like a filter option where I can select one or more other lists, to find films that appear in both lists.
For example, if I’m viewing a list called List A, and I want to see a film that is in both List A and List B, I would like a filter option when viewing list A where I can select List B, and now see only films within List A that is also in List B.
