Plugin Request: Show kanji/radical for wrong answer

When I give a wrong answer, for example when 矢 is shown, but I type “fault”, it displays what “fault” would have been (“失”). Same for radicals and vocabulary.
Maybe even for kanji, although I suppose that’s probably a long list of kanji for any given onyomi, so it may not be as helpful.
What do you think, would this be helpful?

There is a script like that, but I forget what it’s called. I’ll have a look around.

It’s [Userscript] ConfusionGuesser


Exactly what I was looking for. Thank you.
