I wish you would do something about the voting buttons and the expand/collapse buttons. They're way too tiny and way too close to other elements in the default scheme used by HN. This is a big deficiency I see with the default HN interface, which makes it less usable as well as less accessible.
Edit: I also see a 3/28 counter and a spinning icon on the top left of the page that doesn't change regardless of which post I'm browsing. Sometimes it disappears if I navigate to another post or page, but it looks like it starts with 0/28 for every post. [This is on Brave right now; no issues with connectivity or connection speed; dropdown menu from the username works.]
