smartclass displays on players and enemy NPCs. Use playerclass for player classes only (there's a default setting for this).
Thanks, I had the wrong tag, it works pretty well now. This is what I was doing:
I'm a minimalist so I prefer to chop out all extraneous info. In this case I only want to see the level first, elite status if any, and finally class if player only. I would have also preferred to see creature type just for mobs but there's no tag for that. Unfortunately, the "[creature]" tag also displays on players.
