From the developer:
TwitterMCE will allow you to post tweets, view friends, followers, timelines, profiles and delete tweets within Media Center. The latest version adds a new video mode which allows you to tweet while watching TV. Other new features are going to full screen mode by pressing the up button on the remote, viewing what's on your home page and viewing when someone mentioned you.
