Something else scroll-related I personally hate: Sticky 'headers' that disappear when you scroll down, and appear when you scroll up. I hate them so much. It hurts my brain to see the stupid thing appear and disappear constantly if I scroll around a page. The worst part is you can't even zap them out of the way with something like uBlock, because then there's no header even when you're at the top of the page. >:( EDI…
This is literally the best ux pattern you can have. It is intuitive - user immediately discovers it when performing the obvious action, it increases the user experience (more text to read) without any real downside. It is the first thing I suggest to anyone when I see someone didn't implement it. I've never heard a complaint about it until now.
As for “no overhead” what about all the code needed to implement this?
Pages of text should be minimally styled for maximum efficiency.
