First off all:
Im not sure if this is correct forum, dont shoot me if its wrong please, thank you.
So, I just got tidyplates (Im a slacker I know) and I just wonder, is there any way to set it up like this: Red plates if any1 not marked as MT or yourself dont have aggro.
Blue plates if some1 marked as MT, but not yourself have aggro.
Yellow plates if you have aggro.
Last I heard, this just isn't really possible via nameplates, due to the very limited information Blizzard passes to the nameplates (the author of tidyplates does a lot of fancy programming to get enemy debuffs/buffs on the nameplates - finding out who's being targetted would be even more difficult).
