I imported a couple personal lists from Letterboxd using Konsesus Pro to sync the first time, then I disconnected the link to Konsesus and now I manually update my Trakt lists to match my lists on Letterboxd.
One list is of movies that I have on physical discs and the other is a list of movies that I have in Plex. Why don’t I just use the Collection feature in Trakt? Well, I do, and I keep it synced with Plex using the scrobbler. But I don’t use it for movies that I own on disc because I haven’t found an easy way to ID those in Trakt to use as a filter (I could tag them but that would have to be done manually which would be tedious). And I don’t rely solely on my Trakt Collection for a list of movies that I have on Plex because there are a few movies which do not match up between Plex and Trakt.
Yeah, that’s what they wanted… since they were asking for something automatically (New Movie Releases), you get all or nothing 
And if that’s what they want, there’s already a calendar.
If they want a list of specific New Movie Releases, that’s of course fine. But they gotta put in the work of adding movies to a list, nothing automatic about it 
I have created and deleted so many lists over the years.
It depends on what I am looking for at the time.
Some of the types of lists are:
- Where to watch the show/movie (the watch now service button is not always accurate.)
- Shows with “unaired” episodes
- The year / decade of the next unwatched episode
- Do they have specials
- Group my shows by when they first aired
- The type of shows I’m watching (Animated, Drama, Documentary, Reality, Competitions, Kid’s Shows, Sitcoms, etc )
There are probably more reasons I use my lists… But that’s what I can think of at the moment.
And some shows may be on multiple lists.
But my watch list is always my most used list. (What do I want to watch at some point.)
Is this accessible via the API?
I use them as lists of movies I want to watch/rewatch but I also split them into separate genre lists to easily find something depending on what mood I’m in.
Things I plan to watch go on my watchlist, ever since I joined in 2013. For the last two years I have been trying to work on more specific lists, such as:
- Comedies and dramas with multiple acting Emmy nominations (ranked by number of noms)
- Award season lists, with shows and movies to watch out for
- “Challenge” lists, like movies from different countries or a horror movie for every day of October
I think lists are a very interesting feature to have, but they feel very “polluted” in here, with lots of “2024 releases” and whatnot lists, instead of “best of 70’s sci-fi” or “biggest oscar snubs”. I’d say this stems from two things: (1) lists being public by default; (2) lack of a list discovery page/feed/algorithm. Yes, I do know the Discover tab has featured lists, but it is still limited.
I’d suggest something similar to what already happens inside each title’s page: the most liked public lists featuring that item are shown first. But instead of back tracking from the title’s page to the list, I think it would be interesting to see a tab of popular/trending/most saved lists and being able to find new shows and movies just by browsing list titles.
