I have absolutely no idea if this is even possible within the search feature because each deck would have its own number of fields, and layouts, but the search feature searches across all fields anyway doesn’t it? So a feature to search all cards across decks for a matching string so that one can manually hibernate duplicates would be tremendously helpful!
Say I get a card come up in a new deck, instead of searching through 10’s of decks to see if I already have it, just having one place I can go to to see if there is a matching field on any of my present decks would greatly speed up my organization! And would help when encountering vocab in the wild too to quickly find a card to push to the front of the lesson queue.
Also, a way to separate decks on the homepage with headers would be nice.
