It would be nice to have card retirement built in to Anki rather than having to rely on add-ons. In a deck’s options there could be a card retirement interval in the reviews tab, right under maximum interval. Any card that reached the specified interval would be suspended and tagged retired. Obviously the default value would be something so large that beginners wouldn’t even notice that the feature existed (just like maximum interval has a default value of 100 years), but those of us who want to retire cards automatically in certain decks could use this. I would find this very helpful. Thanks for your time.
