Hi! I'm using Mochi for language learning and the most common problem I encounter is that, as my vocab list gets bigger and bigger, I don't know if I've already created a card for a given word. Right now, it's tedious to double check by exiting the new card window and searching the deck for each individual word. It would be amazing if there was a feature or toggle that warns you if you are adding a card that's identical to a previous card, or a search feature that scans your decks for potential duplicates to delete. Thank you –– this is a great program and I'm so glad to have stumbled across it!

Seconding this!
