it would be very convenient to have an infinitely long practice set. that way, one could just keep going and forget about time (and be more likely to stick with it and get more done). maybe, after every 10 questions, one gets a new heart. basically, i would like a script that skips all the unnecessary information (you earned 12 points etc.), and does not stop the flow. of course, the algorithm would have to be adjusted, to ask questions that already use the input one's given a few questions ago (instead of having an infinite set where one practices the same 10 words over and over).
