It would be perfect if WK had a feature that tells you: “Careful! This word reads the same as…” when learning new vocab.
Like I just realized a few levels later (and messed up a Burn) that 公告 has the same pronunciation as 広告. Normally, when doing reviews, you subconsciously know it, but you don’t somehow realize the comparison? If it makes sense what I’m saying
Other that comes to mind is the jisho / jiten block of words which are really messed up (though the first kanji gives it away, but maybe it’s not obvious at first).
I’m just saying, right now it’s an active individual endeavour, trying to find all the similar words and connecting them. And more of a coincidence when you do find it. I do this anyway whenever I’m studying something, not just Japanese. But a lot of times, you entirely miss this and then have an Eureka moment 1 year later. It’s much easier for memorization to find the patterns in everything, which is exactly what this would help with
