I've been using "Reddit-Style Comments for Hacker News" [1] for years, works great. 1: https://github.com/andrewheins/HN-Comment-Hider https://github.com/andrewheins/HN-Comment-Hider edit: This has the collapse button between the voting arrows and username, just like reddit. Seems like something minor, but it's a big detail. (1) I'm used to that location from reddit, and (2) it doesn't move, which isn't the case with many other extensions that have it on the end.
