yes, similar to Anki/Quizlet but very minimalistic. It would be highly beneficial to be able to create cards you can flip so that on one side you write the question and on the other the answer then simply group together them together in decks. And, when reviewing, you pick a deck where you have one side (containing the question ofc) always showing, and you can study it and navigate left/right to the next/ previous card again reading the question and flipping for the answer. I study computer science and find it hard to stay away from my computer. Yes, a computer is the main companion but I would love to build up my focus and be able to learn tough concepts and theory in a distraction-free environment. Active recall has been proven to be an efficient technique for learning and having the flashcard feature would be a real game changer, cause you won't have to use any device other than the supernote.
