Nope, I just use HN search (hn.algolia.com) but I have software that makes it faster and does the formatting - yes, it's a browser extension that I've been using for moderation and adding to for, gosh, coming up on 9 years this fall. See https://news.ycombinator.com/item?id=27236708 and the other links there for more information if interested.
I'm going to make it so any HN links to past threads will render as "title - link - month-year - # of comments" or something similar.
One of these years I'll publish the browser extension too, and the Arc-over-JS implementation it's written in.
