Great ideas! I'm looking forward to features like these.
It would be nice to have an option to only show debuffs that the player can dispel. As a priest in-game, I don't need a poison or curse colored border around the frames because I can't cure those, only diseases and magic. And having too many indicators can make it harder to detect the more important things.
If this could be added, I'd gladly take out all of my many Grid addons and just use nUI's unit frames
