When Google launched an e-mail client back in 2004, the company best known for its search engine completely changed the way we think about e-mail. While Yahoo! and MSN were offering users mailboxes measured in megabytes, Gmail users had an unprecedented 1GB of storage. Messages were sorted by filters and labels and not folders. The threaded message view made it easier to keep up with conversations, and a machine was reading all of your e-mail to serve up relevant ads.

While Gmail inbox sizes have continued to grow, the user interface hasn't changed much in the last three years. But it looks like that could soon change. Googling Google reports there's evidence of a "new version" on the horizon.

Google relies on users who speak multiple languages to help translate the text of various Google services from English into other languages. One anonymous user was translating some Gmail language when he came across a box that implied a selected group of Google beta testers had access to a new version of the Gmail interface. We have no idea what's different in that version or how long it will be before we see a wider release.

We're hoping for folders. Or a Hello Kitty skin. Either one will do.
