Perfect script... Without any unnecessary clutter... Simple & useful...
All in all, this is a good script to use with the New Twitter interface, so the review works from that.
It lets you see at a glance which tweets are new, provides a way to retweet with comments and — best of all — reloads the time automatically without reloading the full page.
However, one big showstopper was that media previews didn't work the way they were supposed to.
To become the best script, all it needs is to add replies like @troynt's twitter script does, and fix the inline media previews.
With those features, it would make the twitter website the best twitter interface of them all.
