Cool!! I normally use two web-browser side by side... I still think is better option, but sometimes sites get really small when I squeeze the windows, so I switch to mobile view, but pitifully there is no extension to make this by tab and I have to constantly switch the views. Your extension could be a solution for me, if it just had an address bar.. hehe... but I guess other people are looking to put more info in one screen. Anyways it seem great! thanks man
