Mike, this is super cool. Two requests: 1) Cantonese doesn't have a flag. Maybe just use the Hong Kong one, at the risk of upsetting the rest of Guangdong? 2)

Mike, this is super cool. Two requests: 1) Cantonese doesn't have a flag. Maybe just use the Hong Kong one, at the risk of upsetting the rest of Guangdong? 2) For hanzi-based languages, it would be super awesome if you could (optionally) display the romanizations as ruby annotations on top of the characters. I know romanizations are there, because they are displayed after getting an answer right, but it would be so helpful if they were available immediately. Thank you again for an amazing tool.
