Tab Bar location
I would like to see the Tab Bar located directly UNDER the Bookmarks bar. When switching between bookmarks and the tabs it is easier to have the two bars together rather than the address bar in-between. Most time is spent working with these two bars and the intervening bar creates a slowdown in the efficiency process. The address bar should be directly below the menu bar (or Vivaldi icon if not using the menu bar) followed by the address bar, the bookmarks bar and the tabs bar.
@BCDoutaz You are not alone.
