I have having trouble identifying and customizing a certain ribbon in Outlook 2013.
The ribbon appears below the search bar and has two categories: All and Unread.
What is the name of this ribbon (if it is a ribbon) and how do I customize the settings to add other categories such as "Mentioned" or "Read"?
Copy and Paste the link below to see an image of the ribbon/section which I am referring to:

Any help would be much appreciated.
