When reviewing, I would like to be able to enable an option to have an N second countdown before automatically marking the answer incorrect. If I start typing an answer, then it can reset or disable the countdown. But I think this would help me get through reviews faster, because sometimes I stare at a card too long before realizing that I should just give up and move on. I’m pretty sure this is a feature of Anki, for what it’s worth.
I already try to implement this system in my brain. It would be handy if the app did it for me automatically.
