It would be wonderful to have a topic tracker button that would allow you to have a list of threads that you are following without having to remember each individual one. Given they do tend to stay toward the top in their respective categories, I just think it would make sense for people to be able to have a list that allows them to go straight to the topic that they want without using the several pages of in between. I have been involved with some other sites and this option allows for much more efficient movement through the site. If this page were to exist I would make it my home page!
eg: button to track topic goes in the middle center of the top of the new thread. then add a button for tracked topics in the top right corner so people can easily navigate to the others that they are participating in.
