Disclaimer: all these apps needs ROOT access and the xposed framework to work. If you don't know what that is, you probably should not be messing with it. That being said, you can do some pretty awesome things if you want to put in the time. This is a list of the xposed modules I am using on a daily basis. There are many others, but since all of them aren't available through the play store, they won't be added to this list unfortunately.
