Similar to the fill in the blank vector for vocabulary, where you can restrict the vector to not appear until a certain mastery level, can we have this with the kanji fill in the blank (inlcuding the definition one) too? I feel like it would be a nice feature to have witb kanji too.
I want to add this, but it is hard to do. Kanji quiz options are far more complex than vocabulary ones, so I would expect that if more fine-tuning like this was implemented, you and/or other users would want to be able to limit it to certain question types, certain answer types, etc.
I feel a strong sense of hesitation when looking at that options panel and thinking "can I add more options here?"
