I know that github is not the best place to say this but it would be really helpful if you added a feature to toggle auto show/hide displays during combat or better yet - on selecting attackable target (hostile or neutral). Your addon is brilliant, thanks for the effort.

Have you checked out /hekili > Displays > (pick a display ) > Visibility ?

Either those options or the ones that appear when you check Advanced should cover that.
