Yeah, its so annoying that I couldn't do the two-finger touchpad swipe left/right for the browser. It's the one single blemish of an otherwise Chrome killer. I would switch to Opera full time but because its absent, I would be back and forth between Chrome and Opera then...
What's even more annoying is that my nephew Could do the gestures in Opera and even he didn't know that it was actually absent in Opera browsers. No extensions, no setting tweaking, nothing, so clearly the devs Could implement it.
