It would be really nice if the website used 100% width or close to it. This is mainly a complaint being on ultrawide, but even on a standard width monitor so much space is wasted. Testing with dev tools its a fairly simple change and the breakpoints all still work, so mobile and smaller screens like laptops would still look fine. This would also solve the complaints of wasted space.
There is far less scrolling this way, the content that is important is more condensed and there isnt these huge empty margins on either side of the page. Why this is a staple in modern design is still beyond me, even working as a web dev. Some margin is fine, but when only 50% of my screen is used it makes no sense.
