I've been working on and off on a Chrome Extension for Hacker News, the extension focusses on improved usability rather than design. I can almost guarantee that after a day you won't want to go back to regular Hacker News. Give it a try, features include:
- Improved readability - Quick inline replies from comments page - Quick profiles with social network info when hovering over usernames - Filtering of stories based on terms and phrases / domain or user - Endless scrolling - Collapsible comment threads - Social sharing for Twitter, Facebook, Google+, Buffer
Forks, improvements and comments welcome: https://github.com/tommoor/HackerNew
