*Great for folks who find the learning retention drops dramatically at 1 month and beyond *Great for books such as the Woodpecker Method (though that one would prolly just need a timer for however long one's cycle is as you wouldn't want the failed reviews popping up again prior to the next cycle).
Hopefully this can get implemented - even though it sounds an extremely tough thing to do code-wise - as it would have a huge effect on learning outcomes, I reckons.
