Is this new?
I don't know if this feature was in iOS 6, but on iOS 7 when you swipe from the left in Safari you go back to the previous page, and when you do so from the right you go back to your current page. It's almost like the swiping from left to right to switch tabs in chrome for iOS.
I came across this by mistake, I thought I had done something wrong. What do you think? Is this new or am I super late?
