Subcategories are presently only supported by the vanilla theme, and even then it's all on the backend of things. The Child categories don't acutally show inside of the parent categories...yet.
This should be a simple tweak though, as @a_5mith mentioned to me the other day.

That would make a lot of sense. Some people don't like FontAwesome or use another icon set entirely - making it more modular would allow for more freedom to choose how you wish.
