@feliae: Do you have it set to not fade out, but hide immediately? I have only heard of there being that issue for inanimate objects in the 3-d world (signs, etc)
My bad. Should have read the tooltips :-/
I was somehow focused on "unit frames" however "world units" is what I was actually looking for :-/
As for changing the text.. I have to investigate that. But from what I've seen there is no "is in my group color" in the dogtag wiki's Color Tags listing. However I believe I can live without "is in my group colouring". I like having bold text though ;) Is that possible?
