Sorry, maybe I'm just calling it "Hot Topics"
In Classic, if you click the recent visitors link, it will tell you which specific forums & categories are being viewed. It will list the forums being viewed the most by percentage (why I'm describing it as "hot topics") For example, from my current board:
http://www.ctfisherman.com/cgi-bin/ultimatebb.cgi?ubb=pntfIn Threads, if you click details for "Who's Online" it will only tell you what mode a person is viewing in (flat or threaded) as well as the category and forum the person is viewing. There is no breakdown by percentage to show you what is being viewed the most by all of the visitors.
I think that is a pretty cool feature.
