I had a chance to skim (I read it in playtest, but it's always interesting to see the final product) part of it -- up through the feats & powers chapter -- and I really like what's in there.
In addition to the feats Shalimar mentioned, I like Up the Wall (or, as I like to call it, the Jackie Chan feat), Last Stand, and Fake Expert ("I bluff the universe").
Slap Silly is also very flavorific, but also very useful.
