The new Facebook design takes advantage of the entire computer screen. The old design did not use all of the screen real estate on either side of the timeline/newsfeed. The columns in the new design go edge-to-edge. On the left-hand side of the newsfeed are the personal options such as a link to your personal profile, any pages you manage, groups you belong to, calendar of events, memories and friends list. On the right-hand side of the timeline is the “birthdays” list and contacts you’ve recently interacted with on Facebook Messenger.
