App Ops Starter

"App Ops" is the Android 4.3's and 4.4 Hidden App Permission Manager.
It lets you selectively disable some permissions for your apps!

This little tool makes it easier to access this hidden Permission Manager.

Update: Google has removed all possibilities to start the "App Ops" on non-rooted Android 4.4.2 devices. Until today no backdoor was found to give you easy access to this feature.
