This would never happen but in an ideal world, we should be able to click on a citation to jump to the part of the paper that is being referenced and each paper page should have a discussion board so we can easily communicate with the authors and group the discussion in one place instead of us having to google to see if there is relevant discussion on twitter/reddit. We can even put links to talks, tutorials, blogs, github repo, demo, paperswithcode/google scholar/open review, background material, a timeline of citations in tree form on the same page(actually I am seeing more machine learning papers that have a project page that does some of these) or even turn it into a mini wiki. I just think html has so much more potential(especially now with LLM we can do semantic search). I wonder if there would be interest in such a chrom extension overlay.
