On the ancient Ikonboard software there was a Moderator Watch function where you could apply an "eye" icon to a Topic that had potential to erupt or go off the rails. It was only seen by Admins and Moderators. Back in the day I found that helpful to keep track of potentially problem Topics as I cruised the Forums as Moderator. I wish it was available on IPS Forums....unless there is something similar that I am missing. 

Maybe this one?

 

Interesting idea

So Charles....does that mean we may see this as a native function someday?
