New interface tweaks for Gmail add tabs across the top of your inbox for better categorization of e-mail.
Gmail gets a useful face-lift
Google announced today that Gmail would receive a notable update across all platforms, with interface tweaks for iOS, Android, and the Web. Though the mobile versions are still coming soon, you can check out the new features as early as today in your Web browser -- that is, if they've been rolled out to your account.
Check out this slideshow to find out if your account has the new interface changes, and get a little more info on how it all works.
Use the check boxes to select which tabs you want displayed at the top of your inbox. It is important to note that you will not be able to create your own tabs -- you can only use the ones offered here.
