Would be great to be able to have an option for Hide in Combat. Additionally useful versions could be Hide in Group, Hide in Raid, Hide in Instance and Hide when No Quests In Zone.

Hey @corporategoth I really like this idea overall!
I'll add it to the roadmap for 1.10.0, I can't provide an ETA for this functionality since I don't know when I'll have time to circle back to this project at the moment (per #91).
