Whenever I came to check the forum, I was frustrated by one thing - I could not see which topics have new replies to them. So, last night, I wrote a little extension for Google Chrome, that fixes it. You can download it here:

What exatly does it do?
1. It shows how many new replies (if any) are there since you last read the topic: http://glitch.fczbkk.com/sshots/overview.jpg Clicking on the red indicator takes you to the first unread reply.
2. Unread replies are highlighted in the topic detail: http://glitch.fczbkk.com/sshots/highlight.jpg
3. If there are any new replies, there's a link at the top of the topic, that takes you directly there: http://glitch.fczbkk.com/sshots/jumpto.jpg
Enjoy.
