I would find it useful if there was the ability to extend the numbered list test one-by-one feature so that each numbered bullet is tested completely separately, shuffled into the due cards, and with its own ease rating. I do not imagine this would be hard to implement.
I heavily use this feature for learning steps in proofs and it is very time consuming to have to relearn the whole card if just one is failed. This would also be better for learning from an interleaving perspective. Thanks
