tl,dr;
add links between similar/synonymous vocabulary.
I just got https://www.wanikani.com/vocabulary/付近 vocabulary (“Neighborhood”) and was all like: “wait a minute, I thought I already learned that and it looked different!” and wo and behold:
Could WK add “Similar vocabulary” (or even synonyms) section to items like that (akin to " Visually Similar Kanji")? It would really help to avoid loosing one sanity and being confused
Ages ago there was similar suggestion deep down in one of the threads:
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun’yomi reading. You learned this reading already so you should be able to read it!
