A couple comments
I'd like to start by saying, I really like the browser. However, there are a few minor cosmetics/bugs/features that would IMHO make it better. 1) It doesn't seem like the browser is using any of the window decorations from the OS. So the Vivaldi seems out of place with all of my other windows. There should be a way to "skin" the browser from default OS settings. 2) No way to change min,max,close buttons from the left side to the right side. The Mac version has them on the right, windows left and linux is on the left. 3) clicking the "V" at the top left of the browser brings up the menu in the top left of the computer screen, regardless where the browser is. 4) No private browsing?
