Because there is no forum specifically for MarginNote 3, I thought I should post this here. First off, there is no spaced repetition. Secondly, although we are offered the option to add audio to the notes, there is no way to turn off the “auto-play” feature. When studying the Flashcards, sometimes it is good to hear the audio, but other times it is not (especially if playing music in the background from another app). I have two images below: the first is from MarginNote 2 Pro, the second is from MarginNote 3. Notice that the first image has two reminders for spaced repetition, but MarginNote 3 has nothing to access it. Also, shuffling the cards, as has been mentioned by other users, should be an option.
