I love that the Fetch API is happening (has happened!): https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API

    fetch(url).then(data => ...)

Not earth-shattering, but much more fun than XHR!

How much does Project Silk improves scrolling performance? Can you "feel" it?

Scrolling/motion performance is the only thing that is keeping me away from FF at the moment - Even dev tools are getting amazingly good.

It's OSX only for now.

For what it's worth, I've just updated on OS X and scrolling feels just as janky as ever.

I can't wait to write it tonight! This is one missing thing on OSX.

Surprised by the inclusion of "CSS Scroll Snap Points": https://developer.mozilla.org/en-US/docs/Web/CSS/scroll-snap...

It basically allows to do scroll hijacking [1] without any JavaScript, just like this: http://blog.gospodarets.com/demos/scroll-snap-full-screen/

Definitely an improvement for me. Smooth inertial scrolling on trackpad has been the reason why I still use Safari on OS X.
