Not sure where I read this, but there are few features that are undocumented on the website probably! But some of them are mentioned here: https://github.com/minimaxir/hacker-news-undocumented

One of the few issues that I've faced is pagination of the comments and occasionally "dang" might pop up to paginate the comments on heavily trending/debated topics.

My 2 cents would be to enable pagination after a set number of comments, so that it doesn't go on and on, on mobiles.

BTW, I really like this kind of website design as its minimal enough to load on terrible connections and easily viewable.
