Suggestion: Visual feedback when guessed correctly

[dieser-niko]

Sometimes I struggle because I don't know if my guess was a guess or not. I just want some visual feedback so I know it was a real guess and not just me getting lucky. I also try to avoid using the hint button, as that would spoil it for me and I can't get the feel right.

If this were to be implemented, it would be as an optional feature of course, not sure if everyone would want to get this feedback.
