New web inspector with animation debugging in Safari 9.0. Looks pretty nice. This will automatically be added to Framer Studio too.
I'm going to the "What's new in Webkit" session tomorrow, will report anything interesting
I'm really hoping they add back the Chrome style "bottom up" performance profiler. That's the only practical way to profile bottlenecks so you can actually *do* something about it when you know that frames are dropping.
