Make the browser swipable too:
Swipe left and right for backward and forward in the browser history while the respective edge of the webpage is shown, just like Internet Explorer Mobile on WP did
Pull down to refresh, just like typically used in android by now
It is weird that the browser falls completely out of the Sailfish design. However, with these functions the most essential operations can be done in swipes too. Instead of being dependant on an always vanishing control bar. A big development!
