Re: Side note: Vivaldi is excellent
Does it have a proper UI layout? (From top to bottom: Title bar, menu bar, nav buttons+address bar, tab bar, page content, status bar, said status bar which displays the target for the link you're hovering over) Does it prevent pages from altering or hiding any of these by default?
 For suitably stretchy values of "proper"
 A UI control to display the current page address or enter a new one. It does not do anything else.
