How to Enable a Pinch-to-Close Gesture for Folders on iOS 9 With a Jailbreak
If you want to use a pinch gesture to close your Home Screen folders rather than pressing the home button or tapping somewhere outside of your folder interface, then you'll enjoy a new free jailbreak tweak called PinchToClose
by iOS developer cole cabral.
The pinch-to-close gesture is a fun way to close out of a folder on your Home Screen, but it's not always the fastest or most convenient way to close out of a folder. If anything, it's really just a way to have your device do something that everyone else's does not, and it's more of a show-off tweak than anything of actual usefulness.
Nonetheless, if the pinch-to-close gesture interests you at all, you can download the tweak for free from Cydia's BigBoss repository right now. The tweak works with iOS 9 devices.
The developer has also made the tweak's source code open source at this GitHub link
