Google Operating System is reporting that Google is testing five new inbox styles in Gmail, on a select group of users. The new inbox styles include classic, important first, unread first, starred first, and Priority Inbox.

This new feature is most likely to help users get introduced to Priority Inbox. All of these features could be accessed by going to Priority Inbox settings, but Google makes it easier with their  first tabs interface inside Gmail. As we all know, Google likes to do these select testings a lot. Today we reported that they’re testing a new black navigation bar on top of their search pages. Are you seeing this new feature in your Gmail?
