[Q] permissions manager vs ApOps topic

I am currently using the app called "Permission Manager". I got it since I'm rather frustrated by all the permissions that the apps claim. Why on earth would the Power app - I guess that's the system app controlling the battery - need to know my location? It certainly does not need it to work - I know that since I have all possible location-related settings on my phone switched off. And that's just one example. Every other app wants to read my contacts. And what's up with the "phone identity"? Does a task list really need that? I can scribble a to-do list on a piece of paper and it won't ask for my pen's identity, right?

Anyways, the Permission Manager integrates itself into Settings->Apps. If I click on any app, it would say "App ops" on top of the screen. I have read however, that App Ops have been disabled. Now, this manager is only able to change some of the permissions, not all of them. And it misses the most important one - net access. Perhaps there is a logical reason for the flashlight app to need net access and location information, but I'm not seeing it. That's why I'd like to have an app that will have a white list of things that are allowed to use the network.

So, is there anything more advanced than the Permission Manager? Mind you, my phone is completely stock, not rooted, locked bootloader, etc.
