As it stands, in the Android version, you can choose from Sans-Normal, Sans-Bold, Serif-Normal, Serif-Bold, Serif-Italic, and Serif-Bold-Italic. I would like to see an option to load a custom font from file. I make a lot of my own fonts and would like to be able to use them in my projects. Currently, I've been hand lettering all my text but feature like this would save me hours of work.
