Paranoid android 4.4

For the past year, I've been using the galaxy nexus as my daily driver, and its one of the best phones I've ever had. Native android is the best experience you can have out of any android skin. Its simple, everything works the way its supposed to without any the manufactures bloatware on the device. Using the galaxy nexus, I rooted and flashed a paranoidandroid ROM onto the device. This gave me permission to change each application to either have the tablet UI, Phone UI or a phablet UI. And not just other the entire OS. I could set it to each application. Over the past few years, paranoidandroid have been leading the pack with features that no other ROM creators have intergrated into their system. Its two features that I really love on the galaxy nexus and that's the Halo feature and pie controls and something that I grew to a custom within days of using the controls. Swiping up from the bottom would reveal the back, home, menu, recent apps buttons. Therefore relieving the screen of the navigation bar at the bottom to give me more screen real estate to work with. I've always say this since the original native OS which implemented navigation bar as a basis for the OS. Obviously google won't integrate this feature into their OS because the majority of people won't know how to go back unless they get their son to show them. But if this was built into the settings where you could have pie controls in the developer options. It would be fantastic and therefore me not having to root or flash a paranoid android ROM onto the device.
The other feature is Halo, which is not based on the game. But in fact a way of displaying your notifications in a little bubble, there's no need for a notification bar. So you get the full experience of the app. Double tap halo, and you can move it around the screen. Hold down and reveals all your info on your phone such as signal. WiFi status, time etc.
Swiping right from the halo and keeping your finger on the screen will display your notifications one by one and then when you've found the notification you want to work on, lift up your finger and it will go to the app corresponding with the notification in a floating app mode, where it floats on top of your already running application.
