Please, this addition would be most welcome. All the other major players in the browser space have this option, and it is the only reason I've left Opera for Vivaldi. Once Opera adds this option, I'm back.

That's a shame, I appreciate the info though. Windows 10 system colors doesn't seem to do anything for the top bar for me. Ah well, I'll check periodically and see if any color change settings have been implemented.

Is there a way to change the colors of the menus and tabs? Changing the theme only changes the background image of the Speed Dial page. Basically I'm looking for something that replicates what the themes do in Google Chrome, where if you make it a dark theme for example, the whole window is dark, the tabs at the top, menus, and bookmarks bar. Am I simply missing something or is there not a way to do this?
