Show HN: Simple "new comments" highlighter for Hacker News

I always find it annoying that I can't revisit a Hacker News comments thread and easily see which comments are new, especially for heavily-discussed topics. Looking through the Chrome Store for extensions which solve this problem yielded nothing worthwhile. I wanted something that didn't burn my eyeballs out and "just worked", with no special features other than simply showing me what comments are new since I last loaded the page.

So I wrote my own on my lunch break. Here's the link: http://axefrog.com/hn-new-comments.crx

Enjoy!
