Facebook Chat Heads & Messenger
Along with the launch of Facebook Home for Android, FB updated the Facebook Messenger App. With the addition of the Chat Head, you can now chat with your friends or quickly send and reply to a message without interrupting what you are doing in another app. The head can be moved around your screen so that it is not in the way of other things. Or, when you are done chatting you can drag it down to hide it.
Although iPhone users don’t have (and likely will never have) Facebook Home, the iPhone did get the Messenger update that enables the Chat Head and they also got the addition of Stickers that you can send to friends. Although they are called stickers, that are really just huge emoticons. I think I’ll live if I don’t get the Sticker update. 🙂
