I made some internal changes. Mainly, all topics that you have already viewed will have a "=>" link on the right side. It works the same way as it was with watched topics.
The link leads you to the last post you read in that topic.
Also, instead of "(new)" there is now "(new topic)" and "(new posts)" labels to indicate if it's a new topic or an existing topic with new replies.
Please let me know if you notice any inconsistencies with links and labels.
