Aura Indicator does not have "custom font" option and grabs the font from the General font setting.
Looking through Aura Indicator settings it does not appear that there is way to modify the font used? It gives me the font size option but nowhere to swap it. Talking about UnitFrames - Group Units - (raid|party|etc) - Aura indicator
Would be nice if it had custom font option for each Unit Frame (grouped or not) and/or be dependant on Unit Frames font like a lot of other options in that category.
