IMO, Hackernews's value is the comment section.

Some things I wish it had while reading comments:

- keyboard shortcut to go to next/previous comment at same level (`j`/`k` a la vim?)

- keyboard shortcut to upvote a comment while it is selected

- memory of which comments I already read, so that when I come back to a comment section, I can navigate directly to the unread comments (useful for conversations that span multiple hours/days). Perhaps also styling read comments differently.

I too wish hacker news had that by default. I use this extension: https://addons.mozilla.org/en-US/firefox/addon/vihn/
