I built ÆHN, an easily customizable user stylesheet for Hacker News. I built this to scratch my own itch. The stylesheet has the following features:<p>- It's dark, meaning my eyes won't burn when I switch to the HN tab in my browser<p>- It removes the elements I never use so I don't have to hunt the HN UI for a way to unhide a comment I accidentally hid<p>- It makes the header sticky so I don't have to scroll back to top when I want to navigate somewhere else<p>- It provides comment indentation guides so I don't have to guess if a comment is a top level comment or a reply<p>The stylesheet is hosted on GitHub: <a href="https://github.com/Kimitri/aehn" rel="nofollow">https://github.com/Kimitri/aehn</a>
