A video inadvertently posted to Google’s YouTube account has given a sneak peek at some of the changes that will be coming to Gmail in the very near future.

The video was quickly taken down but the guys at Google Operating System have snagged a mirror for your viewing pleasure:
The new interface probably be available soon.
