I'm so glad that I'm not the only one asking for this. I don't understand what the use-case is. Why expend all that energy to make a custom native UI platform when all you end up doing is breaking the standards for my native OS? On Windows, Internet Explorer is the only browser that just gives a simple native window. Chrome and Firefox both cause issues because of their custom drawn windows. I don't see any reason to use Vivaldi if they're going to follow the same path.
