Apple redesigned how the App Switcher looks like and act in iOS 7 with inspirations from certain classic jailbreak tweaks like CardSwitcher and the old boring bottom grey switcher has gone. But have you ever been bothered with iOS 7 for scrolling through all the way to the left and right to get to certain page in the App Switcher? Or have you been annoyed with the narrow iPhone screen that is only able to display a little bit more than one app card? Unfortunately it is not easy to go back to iOS 6 classic app switcher easily now.
GridSwitcher is new jailbreak tweak from tom-go that changes the stock iOS 7 horizontal card switcher view to a grid view. It has no option to configure. Once installed you are good to use.
