This is my idea for a next version of iOS. A feature which would be immeasurably useful would be a back and forward gesture in Safari. In my opinion, this should be implemented in a similar way to how it is in OSX Lion, where you swipe with two fingers (3 may be better for iPad) and it goes to the previous page. The real time animation which simulates as if you're dragging the page from above to reveal the previous one below which is in Lion would also be a great bonus! Reaching for the back button can seem tiresome and tedious if you use them often. It has greatly booosted my workflow/efficiency on the Mac. Any opinions?
