This addon sets Hacker News' colour theme to Dracula. The comment/thread UI is also improved, with vertical lines simplifying the indentation of comments. The topmost comment has a purple line, while all child comments have blue. Post OP (original poster) will be highlighted yellow and have [OP] tag for easier recognition in the comments.
