1. Customizable quick setting toggles
This was something that Android Lollipop was severely lacking. Many OEMs such as HTC, LG, and Samsung have allowed their users to customize which quick setting toggles get to live in the notification shade, but Google lagged behind. This time around, Google included it in the Developer Preview, but it takes a little work to unlock it.
You must have Developer Options unlocked, so all that takes is tapping the build number of your device seven times. Once unlocked, head over to the developer options and enable “SystemUI tuner.” Now, there isn’t anything else in there as of now, but I expect it to expand throughout the Developer Preview updates.
Currently with the quick setting toggles, you can add or remove them, All it takes is a drag and drop to re-organize them as well. The amount of toggles may expand in the future to include third party apps.
It might include things such as changing the grid size of the home screen, changing the layout of the app drawer (horizontal vs. vertical). It also wouldn’t surprise me if you are able to download developer made plug-ins to customize the device. It’s a long stretch, but anything is possible at this point with two more updates to go before the final release. Imagine SystemUI tuner like a variant of Xposed Framework.
