I think that it’d be nice if we could add some kanji/vocabulary, its reading(s), examples, just like WK’s.
This way we could add some specific words that are not on WK but we want to learn the Cabrigator’s way.
For example, I love the Monogatari series, but, as everyone knows, Nisioisin uses a lot of different kanji.
Another example could be the rest of N1 kanji/vocab, or even one’s field of study’s vocab.
(Yeah, I know about Anki, but I’m just way more used to WK).
