Improve actor seen page

The Seen page for actors is currently really impractical to use. If my main purpose is to easily see a list of movies and TV Series an actor played in, and I visit the Seen page, I need to scroll through a potentially very long list, and detect the few entries I've actually seen. For example, Emma Thompson's page has 400+ entries and I've seen only 5, and to find out which ones, I need to scroll through the entire 400+ list to find out what I'm actually interested in. Just like there is a checkbox to "Hide titles I've seen", perhaps there could be an option to only show titles I've seen. Moreover, a checkbox is an awkward control to regulate this, I would suggest having buttons that perform these functions instead. In addition, as another idea suggested, I also believe the seen page would benefit from being able to sort the items. Alphabetically and chronologically are both useful. Being able to sort by seen state would be another way to enable the user to group the titles they've seen or those they've not seen. At any rate, currently the titles seem to be sorted randomly by default, which is confusing and not useful for any use case. Being able to choose only one title type and one role type seems like an unnecessary limitation. Perhaps the dropdown lists could be replaced by lists of checkboxes, so that the user could select a combination of, say, "Actor" and "Self", rather than just one at a time. Finally, I find that including episodes of TV series together with movies adds a lot of clutter to the page. An alternative would be: each series is listed once, and under that, indented, is a list of all episodes that the actor in question has been in, sorted in the same way as the outer list.
