Enable System UI Tuner

Long pressing the settings cog icon, enables easy access to System UI Tuner which consists of a set of experimental features and settings on Marshmallow. 

Move Toggles in Notification Drawer

A single swipe down from top of the screen, in the Quick Settings area, expands a little further, displaying battery percentage, carrier information and shortcut to the settings menu. Users can move around the quick settings toggles and add new ones in the notification drawer by just holding on one icon and moving it by going to Settings->System UI Tuner->Quick Settings. This eliminates the issue of clustered status bar with Bluetooth, Alarm icons and many more.
