A feature called “Cover Feed” (much along the lines of HTC’s Blinkfeed) now features on lockscreens along with photos and status updates to populate and make it look more aesthetic. Normal applications on Android can still be accessed via an app tray which is now given second priority on the Facebook homescreen.
Chat Head are small shortcuts to messaging that are highly engaging as they display conversation bubbles on the home screen or any other application in that matter that is being used. These chat heads open up to show entire conversations with an unread message count.
