I'd imagine something to do with the way protocol works?... But I'm not exactly sure. With this version of Plus! with custom names, you can make them bold, italic, and colored.... I know there's something in Plus! Tweak that could change the font... Or at least there used to be. I'M NOT sure if it's in it... But I remembered seeing something. And if it is it's for all contacts... not just different ones you'd chose for different fonts.

That's the thread if you'd like to try it.
EDIT:... I'm probably wrong... believe Matty
... but you could try it.
