Practice weakest words needs some work
The lingots are nice but your "Practice Weakest Words" algorithm needs work. It does not prompt for the words, variations or conjugations that have been least practiced or seen. I'll happily donate all my lingots for a competent vocabulary review.
I agree - i can't seem to resurrect those words from three weeks ago that I saw once but never again. Every day I have the same things coming up - if I have to "pass a bowl to the cook" again he'd better duck!
