I second that. The replies link really needs to exist. If it just got relocated it would be awesome if you could tell us where.
Also, while being able to re-size the message box is cool, the default should be larger.
I like the overall color scheme and design. The blue bar at the top takes up a lot of real estate, and I don't quite know what to think about the floating bar, but so long as I get replies back I'll be a happy camper.
