The good thing is that different people can use different UIs. Eg. people like you who prefer the density can use HN and others who prefer the readability and clickability can use FilterHN.
The long term vision (https://gearsyfounder.substack.com/p/informal-business-plan-...) here is to provide you with a personalized feed. So that you could say things like "show me less posts about politics" or "show me more posts about front end web development".
But right now it's just a redesign of HN. I'd love to hear whether you guys think.
Notes on some design decisions I made:
1. Mobile design where it's easy enough to click things.
4. Don't show the author or time since submission (it's visible if you hover over the karma or if you go to the show/comments page of the submission). The more stuff on the screen, the more it takes away from the content you truly want to see: submission titles.
5. Link to HN for features I haven't gotten to yet.
6. Make "More" link more prominent and visually interesting.
7. Otherwise lean towards keeping the original design and personality of HN.
