Don't know if this has been answered already, but here goes. I (think) I used to be able to make nameplates show up automatically when I entered combat and then they'd turn off when I left combat. Am I mistaken? Is this option available and if so, where?

Thanks.

Using most recent ag_uf and ace2 as far as I know. Buffs/debuffs are not showing up.
