One of Facebook Home's features, chat heads
, is named aptly for the way these items appear on the interface. Every time a friend messages you (Facebook or text), their face pops up in a little bubble at the top of your screen along with a preview of their message. Users can move these heads around to wherever they like on their screen, or tap on the head to view the conversation. Reply to that conversation directly from there without leaving the app you're currently using.
Facebook Home makes it possible to switch between multiple messages within apps, too. Multiple bubbles will appear on the screen, and users can collapse into a pile on the side of your display so they don't take up room. When you're done with a conversation, you can simply throw the head away at the bottom of the display. The heads follow you from app to app, and even if another message comes through you can tap on heads to switch between the two conversations.
