I've come to heavily rely on Safari's back/forward animation, which allows me to not only navigate quickly between visited pages, but also reveals the content of the previous/next page while on the current page without refreshing, thus greatly facilitating comparisons and plain-old reading. Once you experience this, there is really no going back -- it's like reading a book.
It is shocking to me Google have still (v4.3) not implemented this fantastic memory-aid and usability feature in Chrome. Since no other Android browser I tried (Dolphin, Opera, Firefox & Puffin) has such gestures by default, is it at all possible to have swipe navigation/animation on Android?
