Firstly want to say I love the app, I’ve found it very helpful.
My suggestion is that there should be a clickable hard link to the Kanji or Vocab info page (i.e. https://www.wanikani.com/kanji/便) in the info section when you get a review wrong.
Something I’ve found that seems to repeatedly trip me up is writing the wrong reading or meaning for visually similar Kanji. I just accidentally typed 使 as “convenient” as I’d only just learned 便 from lessons.
I know there’s a “visually similar kanji” section when you go look the kanji up directly - the problem that I’ve found is that because there’s no direct link to the kanji page anywhere in the reviews section - it’s rather inconvenient and breaks me out of the “review zone” to go searching through the various level brackets (1-10, 11-20 etc) to find the two kanji that I’m looking for to compare them.
Please correct me if the link is really obvious and I’m just not seeing it
