Ask HN: What HN tooling do you use to enhance your HN experience?

I use https://hackernewsletter.com/ to keep up, F5 bot to know when I'm mentioned. Made my own chrome extension (I wont plug here, its in my post history) to ease front page refresh, article search and post submission.

I've often wanted to follow specific individuals (aka be notified when they post) and I wonder if there's tooling for that. Also wondering what else I don't know exists?
