Back in June, Google announced a big Gmail redesign. While Google has not officially announced its launch yet, the following video appears to have just leaked from the company, and is trending on Google+.

In the video, Google’s Jason Cornwell, who wrote a blog post about the redesign in June talks about it some more.

“To start, we’ve completely redesigned the look and feel of Gmail to make it as clean, simple, and intuitive as possible,” he says. “In addition, the new Gmail automatically adapts to fit nicely into any size window. If you prefer a specific display density, you can easily set that as well.”

“Some people use a lot of labels. Others chat a lot,” he continues. “You can now adjust the size of the label and chat areas to meet your needs. Even if you do nothing, Gmail adapts to you. The new look allows themes to really shine. We’ve updated many of them with new high resolution imagery.”

“Conversations in Gmail have been redesigned to improve usability and to feel more like a real conversation,” Cornwell says. “We’ve also added profile pictures, so that you can see who said what. Searching is at the heart of Gmail. The new search box makes it easy to customize your search to find exactly what you’re looking for. You can also create a filter right from the search box.”

The design feels a lot more Google+y – particularly with the profile pics and whatnot. It will be interesting to see how people like it once it has rolled out.
