This bookmarklet marks where the bottom of the page was when you press space to page-down[1] I modified it so the marker is not a red line, but a transparent gray block marking the part of the page you've already seen. (Sometimes I couldn't find the red line before it fades away, and I find the gray block less distracting.) Then I added it to ViolentMonkey (user script) so it's always activated without having to click the bookmarklet.
