I have started to follow Hacker News more than ever, and a few challenges that I have are: no dark mode, when creating a discussion, there is no easy way to add new lines (no multi-line input field), hard to identify OP's comments in a thread, etc. In other words, I am generally wondering if there are extensions out there to improve the default HN experience.
