The current navigation bar shows all users in the same country shortcuts to the same five things, which in the United States are the News Feed, notifications, menu, Watch, and Marketplace icons. In the new version, which Facebook will be rolling out to users over the next few weeks, according to an article in CNET, the News Feed, menu and notifications icons will remain, but the remaining icons will show the stuff the users use the most. This will happen automatically at first based on usage, but eventually, people will be able to set them up the way they want.
“We want the shortcuts available in the navigation bar to reflect how an individual uses Facebook,” Product Manager Alexa Andrzejewski said in a statement to CNET. “To that end, we’re customizing mobile shortcuts so everyone can more easily connect with their most frequently used products.”
