It's been a long time coming, and I've gotten plenty of email requesting the new features that have finally made their way into BeTwittered. Most notable are the reply and direct message functions. The interface also got a bit of an upgrade with nice icons/buttons, and now by clicking the "Show More" button on a tweet, you can get extended info about the sender and the tweet. The "show more" button, by the way, is how you also get to the reply and direct message buttons.
Next on my plate? I'm looking to add a "replies" tab so you can see who has sent you a reply. Also, I will be adding a "back" button so you can page through your tweet history. This has to wait until Twitter turns this feature back on. Right now, it's just not available to us.
