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.

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.

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.

What i find really annoying with using trakt, is the way you have to seperate shows or movies into seperate list for your personal "status" on that show (Like i need to make my own list for shows that i have dropped, have on hold or have completed (and you have the default Watchlist for shows you want to watch.))

So what i think would immensely help organize our shows/movies, is to have a more "Complete list" of every show/movie and their own "Status", like they do on MyAnimeList. (Or we could just have a new system of "tagging" shows, so these "Statuses" are more clearly visible.) An example of this is the way i have organized my page on MyAnimeList: https://myanimelist.net/mangalist/davidpeder2

Here you can filter every entry after their status; like "watching", "on hold", "dropped" or "want to watch", and you can easily see what their status is. I also find this way much easier to find out how many episodes you have watched, than to hover your mouse over the shows to see how many episodes you have watched/how many times you have seen it. Here you can also give comments on the specific entry.

This would make organization much easier, and would make it so that i dont have to have multiple tabs open just to see everything i am watching, have completed, have on hold and have dropped.

One area where trakt currently is severely lacking is keeping up with your "network"/"friends". The number of people you can follow before the dashboard looses it's usefulness is probably a mere 3 users. Capping out at 12 recent items is quite harsh. A single casual user these days can probably nuke that feed in an evening alone (watching, collecting, commenting, lists, etc.). Going above that you can pretty much scratch that area of trakt. If you want to find out what certain people are enjoying you are forced to click on their profile AND "study"
their history (at least for TV data).

What could be improved / expanded:
- Filter options. However not just a single selector but checkboxes for the different types of interactions.
- Different display views including a text/icon list. (the current one is overloaded and not easy to read)
- Condensed user actions as I once suggested before V2 (http://support.trakt.tv/forums/188762-general/suggestions/3561062-condense-activities-dashboard).
- User independent views or data. Ex. most watched shows among friends in the last x-days, highest rated.
- Recent feed for each of the users (as an expanded view).
