As of right now you can mark a item as collected with one type of metadata bluray/dvd/digtal ect.
Myself I have multiple editions of a movie like a bluray and a dvd or bluray and digital copy or all of the above.
It would be nice to either be able to mark a movie/tv show/episode as collected more than once.
Like watch history with a view all button and the best quality shown on the main page.
Or be able to select more than one option under format.
I personally prefer the former because it represents what is an entirely different copy.

Hope this makes sense.

I'm an Android user and I've often searched for native apps that integrate with Trakt but I always end up returning to the Trakt website itself because it offers more features, is more robust & also is quite quick.

For a better integration into the OS I always add the website to my homescreen to have the Chrome bar removed and have a separate entry in the Recents with the Trakt icon.

Now over the last few years/months Google has improved upon this simple add to home screen feature and offered "deeper" integration.

For example PWAs can show up in the app drawer (not just as a shortcut on the home screen).
PWAs get an own "App info" screen where we can manage notifications, permissions, storage among other settings.

A good example of this would be the Twitter's PWA.

Also the current Trakt web app shows a small Chrome icon in a corner which those other web app don't anymore.

I'm not exactly sure how these features can be activated but it should be fairly simple.

The horizonal cast list has some issues worth mentioning:

1. Captions are very small and often abbreviated, requiring mouseover;
2. Emphasis on pictures makes it look nice, but trying to find someone by name or character name can take more time than necessary if the cast is extensive;
3. Horizontal scrolling on mobile can be problematic (more often than not the touch sensor registers the slight vertical move of a finger and starts vertical scroll instead of horizontal), and even on desktop clicking and dragging the scrollbar is clunky compared to using the scroll wheel.

I'd much prefer it to be replaced with vertical list, perhaps double (or even triple column on desktop if it is possible to fit the names beside the picture using normal-sized font without abbreviating), and single column on mobile. Adding the right arrow icon to the Actors header, leading to full list on a new view could be a satisfying solution as well. The list on separate view could be sortable by actor name and character name.

By the way, that little right arrow (the class="trakt-icon-circle-right" element) could be a bit bigger and easier to touch on mobile.

I find it really interesting to see how other users have rated a movie or show and how they rated others. Unfortunately, trakt currently only surfaces this information sparingly (AFAICT only for friends on an item's page and in a user's ratings tab). This is especially apparent when browsing the site while not logged in.

It would be great if trakt could show a user's rating when a movie or show is display in a user's context, i.e. on their profile, history, lists etc.

E.g. the profile already shows a user's recently watched episodes and movies and that would be a great place to also show how the user has rated it.

This could be done similarly how an user's own rating is displayed, e.g. by adding a blue corner with the rating to the bottom right or top left. Or it could augment / replace the global rating in the bottom bar.

It'd be great to be notified on the Dashboard when there's a special showing happening near me of movies that aren't new releases. There are lots of small, independent theaters that do special screenings, re-releases, or film festivals, or whatever.

For example, I had Vertigo on my Watchlist, and there was a showing at my local theater, and it would've been great if that appeared on my Dashboard.

I know getting to that data is difficult, and a lot of it is probably impossible to get in a usable, automatable format, but there are a lot of showtime sites that probably have APIs, or you could even allow people to add Facebook feeds or iCal links to their favorite theaters, so you gradually build a database of smaller theaters that way.
