The Conditional Enhancements category has been added to the HUD Layout interface.

From the System menu, open the HUD Layout interface. After selecting any of the Status Info categories from the dropdown menu, open the UI Element Settings menu. Then, under Layout, select "Split Element into 4 Groups."
Now if we could only get an option to display debuffs only (instead of the 30 dots) on mobs that would be great. I don't care about other's dots, but I do care about knowing when Trick attack is up, or Reprisal is on a boss.

Would also be wonderful for an ability to lower mob flashy spell effects. I can lower them on players but not mobs.
