Safari in iOS 7 now gets a fancy 3D based tab view that not only looks nicer but is useful as well.
To access the tab view, tap the icon at the bottom right corner. If you don’t see one showing, simply swiping your finger down a little bit will bring it up for you. Note that, make sure don’t stick your finger on the screen when you do the swipe-down motion.
To close a tap, normally you would click the X mark on the tab that you want to close.
But in iOS 7, you can also easily swipe the tab left to quickly close it. Isn’t it very cool?
