Google accidentally posted a video of a new version of Gmail that features a revamped look, redesigned conversation threads and improved search to its YouTube channel. The new version of Gmail has been in the works since June this year when Google began tinkering with its features.

This unofficial video, which features Jason Cornwell, user experience designer for Gmail, highlights other upcoming features in the new revamped Gmail. Google has since made the video private but not before YouTube user crlsndrsjmnz uploaded it to his YouTube account.
