A feature that in Vivaldi is missing is a full screen Web panel.
The Web panel works great and the function is very useful, but I wish you could also use the Web panel website or function of the Web panel if you maximize a video or goes on the full screen mode (F11 Key).
If you like my idea, then hit the like button in the post, to get likes in that topic and bring the feature in this browser fast as possible (because the likes says if the feature will Vivaldi take or not.)
Have a nice day.
You can access the web panels when you are in fullscreen, if you press F4 to display the side panel.
