Cool script! Thanks!

I like the tab completion but noticed that it only works for friends that have tweets that are recent and being displayed on the main page, and that if they do not have a recent tweet, that is not being displayed it will not work. But other than that very cool. just so you know, Twitter has announced that it will be supporting retweets soon.

It would be cool to add keyboard shortcuts like Google Reader (j/k for next/prev, f for mark as favorite, r for retweet, t for tweet, etc). Otherwise, excellent script.
