The Little Things
Those are just a few of the features coming with Android Marshmallow for Nexus devices. There are a number of other important features including a ton of smaller, lesser known changes that we're extremely excited about.
Salman Ahmad has put together a list of these features, big and small, and it will give you a pretty good idea about how big Android 6.0 actually is going to be for Nexus smartphones and tablets.
A few of the features that have us excited are the new RAM Manager, a System UI tuner that allows you to quickly customize your quick settings, and the design changes to the volume controls. We hated Lollipop's volume controls and Google's made improvements in Android 6.0.
