And I do mean sexy. This thing is hot hot hot, and adds countless features I’ve desperately wanted for ages. Better organization and information tools for your games library. A seriously awesome and genuinely useful in-game dashboard, complete with a clock and a full Webkit based browser for quick info lookups. Nifty little extra info bits on the nicely reorganized and much more informative store.
It’s an opt-in beta at the moment (find it in your steam settings), and there’s a bit of a bug with some users that breaks all the web stuff (there’s a fix here).
I recommend checking it out. They’ve gone that much farther into making Steam more than just an IM program attached to a store.
