I've started using a bookmarked topic list to keep track of topics I'm active on or interested in. It would be great if the topic list on my bookmarks page would show the same "New replies" notification as appears in the main topic lists.
All of these suggestions are meant to be put on the bottom of some list or other for you to get to when there's free time - I hope none of them end up meaning you don't get time to enjoy life or actually RACE!
