Well slap me and call me Susan.
Definitely ELVUI.
As we are talking about addons, is there any way to set a max range to nameplates? For example, at botanist during the boss i keep seeing the nameplates of the add that were not cleared, and sometimes it makes me to missclick on to them :/

What UI frame do you prefer?
