The thing I'm most impressed about is the speed at which this has come out.

It seems like gmail has previously changed at a glacial speed (for better/worse).

I hope they continue to improve the UX of gmail on a continuous basis.

Google is in the midst of the largest redesign in its history. There may be more to come. Here is a cool talk about this by Jon Wiley, Lead Designer for Google Search: http://vimeo.com/29965463 He talks about GMail around 11min10s

It gets improved continuously internally, not sure why they're slow to push the changes to the public version.
