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:

- It's dark, meaning my eyes won't burn when I switch to the HN tab in my browser

- 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

- It makes the header sticky so I don't have to scroll back to top when I want to navigate somewhere else

- It provides comment indentation guides so I don't have to guess if a comment is a top level comment or a reply

The stylesheet is hosted on GitHub: https://github.com/Kimitri/aehn
