Facebook is certainly not a company that chooses to rest on its laurels and they have proven this by offering updates to their Facebook app periodically, be it on the mobile or desktop platforms. One of their latest changes would be the introduction of Chat Heads that changes the way you message one another in Facebook on your mobile device. Well, the team behind the Paranoid Android custom ROM are currently developing a system which enables you to perform additional multitasking, calling it “Halo.”
Halo would ride on the Chat Head concept of a persistent bubble which will launch the Facebook Messenger app right on top of your current app, universalizing it in the process. Should there be any app that sends a notification to Android, it will head right into the Halo bubble, and you can tap on it in order to check out the pop-up window which allows you to access the SMS, email, or whatever else behind the notification on the spot.
This particular feature is not quite ready for prime time use among users yet and should it be, you are still required to install the ParanoidAndroid custom ROM. This is definitely not child’s play, but the reward is worth the effort methinks. The team behind this Halo shebang were certainly inspired by Facebook, having written down, "let us express our absolute gratitude to Facebook for this idea! We loved it from the start."
