Want more than 30 news on a main page, because on my vertical ultrawide it looks half-filled. Also remove limit of comments on one page for same reason.
BTW, the HN is the least pesky web-forum I've ever seen, you will have hard time to improve it.
I will check if I can embed this feature to Alex’s idea. Again, I will submit another Ask HN as there does not seem to be much interest for a Chrome Extension. I do not want to create something that does not contribute much to the community.
