Tungdo did something interesting.
But I’m not interested. It was like building bbpress theme, or buddypress theme.
I think it’s something wp core need to do. If wp.com use wp.org to steal post format from tumblr. They should do it again for better admin UI. (And they are doing it right now)
However admin theme plugin (alpha) by Justin is awesome. (Didn’t know it was so simple)
