I asked this over in the UI forums but figure ask here too.

Friend of mine is looking for assistance in tracking his DoTs as a healer. He wanted to use his focus target frame for it, but there's no way he can filter out anything on it, and other folks' debuffs are pushing his DoTs off the visible list.

Suggestions? Or is this just something he needs to deal with until they give us addons? Because you can filter out others' debuffs on the *target* window, but not the focus target? Unless there's something we're missing..
