Id like to have the option to disable the outline of npc professions when in name only mode. Right now its the only thing keeping me from using it.

The option seems to be missing in the configuration... I will put this on my todo-list.
In the meantime, you coud try the following in chat:
/run print(Plater.db.profile.plate_config.friendlynpc.big_actortitle_text_outline)
Remember what this prints in chat, probably "OUTLINE", so that you can reset it if you want.
To set the outline:
/run Plater.db.profile.plate_config.friendlynpc.big_actortitle_text_outline="NONE"; ReloadUI();

Added settings with #49 - will be available in the next alpha / release.
