Move address bar on the same line as tabs to give move space for websites on desktops

For a long time I have wanted the address bar sitting next to the tabs and act as a flex-box.

When there are lots of tabs open it moves the address bar down and looks the same as it does today.
Also the menu and the controllers could act the same.
Could be an opt-in in the settings section as I believe everyone wouldn't like the idea. But some might.
