A suggestion: just like how WK shows you vocab that uses x kanji during the kanji lessons, I think having a script that showed you vocab using the same kanji readings for vocab lessons could be very useful.
For example: imagine that you’re learning the word 歌手. The script would tell you something like: “Hey, here’s some more words that have the same reading for 手 (しゅ): 助手、選手 and 握手!”
I find that learning new words using the same reading for the same kanji really makes it easier to learn those words. Your brain kinda groups these words together.
Here’s an example from Maggie Sensei using the same logic:
@koichi sorry to tag you, just in case you find this interesting (aka wanna add it to wk).
