I personally am not a fan of using the algorithm for the order or for when to re-attempt my flash cards.
I write my flashcards in groups and tend to do them as I see fit, have time, when the exam is close etc, by clicking on practice - all of these rem.
Currently you can practice the flashcards like I suggested, I just have some recommended improvements. The random is only pseudo random, as its the same random every time. I would like to see this become proper random.
Also, as-well as a true random, I would also like to be able to practice my flash cards in the order they have been written.
cheers,
Jens.
