Sync watch list from other subscription services.
You can sync Netflix using https://simkl.com/apps/import/netflix/
Unfortunately if you watch a trailer or 1 minute of the episode or movie on Amazon, it will also say that you watched it, so can't use it. Amazon also has security password questions often, so not easy to update in background.
When you find a page with a watch history on any of the requested services, please let us know at firstname.lastname@example.org. For now, none of them have an API or a page with your watch history.

At least in Europe. Interface looks similar to Netflix, maybe this is the same codebase and API?
push for Disney Plus

Have no idea how hard it would be, but a few other subscription servies that would be cool to add sync:
