In the catalog it's possible to set filters to only view those that are close captioned, or hide things that have already been purchased, but I think more would be useful. Especially with RiffTrax Friends, I have access to hundreds of things I didn't individually purchase over the years, so the ability to quickly filter out things I've already seen (or maybe filter TO things I've already seen) would be useful. It's also possible to set movies to a Watchlist or as Favorites and it IS possible to see those lists, but I think they might be more obvious as filters in the catalog view as well. I think that would be a bit more straightforward than having them available from a dropdown menu at the top of the screen which goes to a different view it's not possible to further filter/sort.
