@soggow it does help but it's not the same thing, not at all.
Chrome does add search engines for each website in which you make a search.
Then, when you start typing the website (i.e: "yout" of "youtube), it will allow you to press tab to search directly into that website, without having to write the full url, name or even shortcut.
I really love Opera and would love to use it for everything, but not having this simple feature by 2021 is a deal breaker for me. And I don't get why. Isn't Opera supposed to be smarter than other browsers?
