If you are on 6.0 marshmallow and want the option to customize your quick tiles then check out this app (Custom Quick Settings - Android Apps on Google Play). Nice little tweak that will work on stock phones as well.

This adds more functionality than turning on the ui tuner, right?

I can't get rid of "Cast". Even removing it from the UI tuner.
