Control Center is one of the more useful parts of iOS where you can easily toggle on or off some of your most important features, and where you can access shortcuts to your device's most useful utilitarian apps.
Unfortunately, Apple wasn't thinking three-dimensionally when they launched the iPhone 6s and iPhone 6s Plus, and as a result, Control Center doesn't take advantage of the 3D Touch display. That's where a new jailbreak tweak release called QuickCenter, which can be had from Cydia for $0.99, comes to the rescue.
