Satoshi said... If you're still up for suggestions, I have another one.Had a look at the scripts: it seems feasible, though I'll schedule this for the release after the next one.
Add the option to put the radicals and kanji in the reviews in the beginning. It can be all radicals and kanji like in this script or just from the current level like in the Wanikani customizer. Whatever you feel is better/easier to implement.
I think I'll choose the first one: it seems easier to integrate and @alucardeck is still active on the forum (I like to receive an explicit permission)
