Next up is the ability to customize the boxes that appear under your new cover photo. The "Friends" and "Photos" boxes are fixed, but you can play around with the others. To edit the boxes, click on the small arrow icon on their right. All boxes that can be moved or removed will have a pencil edit icon appear as you hover. Hitting on the pencil brings up edit options to remove or swap boxes. To add a Facebook app, or one of the new social apps, click on the plus sign on an empty box.
