What I want is for the address bar to give me a really quick way to jump to existing tabs, if I start to type in the address of one I already have open. The entire reason my tabs get out of control is that at some point I get enough open that I start to lose track of what's there, and repeat myself. End up with like 5 AWS tabs, only one of which I'm actually using, stuff like that. So finally I just bookmark the whole set ("just in case"—I've not once looked back at these, in almost a decade of working this way, though I bet there's some great shit in there) and start over.
Apple's "tab groups" approach being a solution, but the trouble is I forget to switch to the correct group for a given site and end up using a single jumbled-up session anyway. It needs better (more automatic, probably) UI.
