We already knew Android 4.3 focused on under-the-hood improvements, but it appears there are at least a couple more hidden features than Google let on.

As Android Police first discovered, Android 4.3 includes a hidden permissions manager, called "App ops," which can prevent apps from accessing certain types of information.
This feature clearly isn't ready for the average user, so Google has kept it well-hidden. You can find it yourself through any app that lets you view Activities, such as Nova Launcher or Activity Launcher. When looking through these Activities, look under Settings and find the option for App ops. If that sounds too complicated, you can just download the Permission Manager app, which is simply a shortcut to this hidden feature.
Once inside App ops, you'll see a list of all your apps, along with a granular list of their permissions. Tapping on any app lets you toggle those permissions on and off. This could be useful if you don't want an app to check for your location, but the app itself doesn't provide a way to turn off location checking.
