Something I’ve wanted for a while in my other browsers, I’d love a “no distraction” mode that ran a simple topic classifier on the last few pages I’ve been looking at, and then greyed out links to pages that were obviously nowhere near that topic. Thinking specifically of the “links from across stack exchange list on the right sidebar of SO” that often draw me into reading about eg DND, Wikipedia rabbitholes, or any page component that tries to get you to lose your train of thought and get lost on that site. Also, the ability to grey out links to domains I’ve decided I never want to visit.
