When a deck is imported to the desktop version of Anki, it comes like this:

I get a massive amount of reviews from people who get confused, because they don’t know they are supposed to click the “+” symbol to view the subdecks.
So here’s my suggestion. Change the behavior of Anki in a way, that decks imported come expanded by default. Full expanded, like this:
Another massive source of confusion among new Anki users, comes from users who don’t realize they have the card order set to “random”, but I’ll save that for another thread.
