Requires iOS 6 or higher
Grabber Enhancer lets you improve your camera grabber on your iPhone, iPod, and yes even your iPad!
It will let you set the grabber to either unlock your device via a swipe upwards, a tap on the grabber, or just have the grabber open the camera as normal.
There is also an option for iPods and iPhones to remove the grabber from the bottom bar and the grabber for iPads will be enabled automatically with the tweak!
Enjoy!
