Hi! First of all, thank you so much for this amazing app and the opportunity for us to propose features and improvements! My feature request would be to add an option to remove the card-definition matching exercise where multiple cards and definitions are shown together. In my case, this exercise makes me remember the card before I encounter it in a one-on-one card-definition session. This creates a problem: when the one-on-one card appears later, I already recognize it from the earlier matching game, and the app assumes I've learned it. But I haven't truly learned it—I only remembered it from that previous exposure. Because of this, the card I supposedly learned doesn't show up again, and the app marks it as learned, even though I didn’t properly study it yet. Thanks again!
