There is something I really love on my surface 2

It's something in IE, when you swipe to the left, it open the last page. It's fantastic, I was amazed when I discover it, I navigate only like this now, and I don't use the arrow anymore. What is fun, is that when I'm using the ipad of my girlfriend (my old ipad), I always try the tricks before I realize that it doesnt work on Ios...

This gesture is so natural, i love it. Now i realize that Im making the same mistake on Xbox music, and Bing News, why don't Microsoft inplement it on each app instead of the Arrow.... what do hou think guys?
