Just a suggestion for the prompt.

Currently it highlights a word containing simplified characters with yellow, and red for traditional.

I think I'd prefer it if it only highlighted the characters that do have different simp/trad versions, rather than the whole word, and left the rest with a white background.

Hmm, interesting. A small change; a little trickier to code. What do others think?

I study both styles as well. If it's an easy change, I guess I wouldn't be against it.
