I personally wish I could combine the tabs bar and the address bar into just one bar.
I'm not sure, was this a thing on the Internet Explorer at some point? My concern is not nostalgia though. I merely just want to have the most amount of space for web browsing. Address bar isn't much useful to me than putting in an address to me. I make it so infrequent, that having a bar as wide as my screen, always sitting on top, almost like an ad, bothers me ever so slightly.
Just my two cents. I'd like to be able to do this.
Thanks, and bye!
