One of my must have features on a browser while using a laptop is: being able to go back to previous page by swiping on the touchpad. It's such a simple and mandatory requirement that many other popular browser have already implemented it, so please consider adding this feature for the sake of this browser, which I love so far. Also, I've seen other people complaining about this for years, why don't you just solve it? I'm pretty sure it's not that hard to do so and everybody will be happy.
Thanks!
