I think it would be very useful to have the ability to save your face design/skin and hair color/hair design just like you can save outfits in the wardrobe. From time to time my daughter likes to join me looking for treasure in the ancient lands but only if I change the character to look like a girl (i.e., in a dress and all pink and purple).
I'd also like the chance to try new facial ideas without worrying the I am going to forget my current setup.
