I just had a dumb idea, think of a vector for words, where like, it gives you a kanji bank and you drag them in to make the requested word(either definition or kana).
It would have like 5-10 kanji(unrelated ones mixed in) and you'd have to build the word. This would help greatly in remembering what kanji is used, and in what order for words.
cause I believe that some of us, at least me, use the JP keyboard and it auto suggests the kanji for said word when typed out in hiragana, which breaks memorization, plus drawing it can be slow and annoying.
Probably not good as a vector, as a vector is meant to challenge a certain body of information about the term, but as a quiz mode, it might be doable in the future.
