While I really do appreciate the improvements in version 2020 Wave 1 in page rendering, I do think there's a lot of things that can be done easily to further improve upon the experience. My biggest wish would be to maximize the space for content on screen. I've attached this picture of what I think can be reduced - I don't know if anyone agrees with me on this, but I know that all of my clients agree with me that you can't see much on screen anymore.
