Hi, thanks for making a polished no-nonsense flashcard application.

On iOS currently the process of importing a mochi deck involves first downloading the file to the files app, then opening mochi, clicking import, browsing to where the file was saved and importing it. This is necessary because the mochi application is not associated to .mochi files, which prevents it from being selectable directly when you click the 'share' (square with up-arrow) button on a mochi file.

I suggest registering the Mochi application as a handler for the .mochi file format, see Defining file and data types for your app, this would make importing from http or email on iOS a lot more convenient as it would eliminate manual opening of the Mochi app and browsing for the file. I think it should also be possible to register for a mime-type that webservers could use and avoid the download completely, but I'm less sure on that front.

Kudo's on the docs btw, they're polished and very helpful for those creating their own decks.
