sorry about the lack of clarity, i’m referring to this. This script only quizzes you once on leeches between two reviews(even if you change browser). it also asks questions thrice and quizzes you on similar items(i think it’s based on the visually similar kanji list) at the same time. quizzing similar items at the same time helped “differentiate” between a many of my leeches.
Yes i’m aware that you can run quizzes but if you do two quizzes you’ll still get most of the leeches you reviewed in the previous quiz and no visually similar items are included in the quiz(unless i missed something).
