It would be really amazing if the following were offered to customize your Glitchen's style:
A Monocle
Glasses (Nerd style, 60's style, 80's style with the flip up sunglasses, etc.)
Mustaches (Pencil, Handle bar, Samurai Guru, etc.)
An Eye patch.
And it would be nice if the facial additions (Monocle, Glasses, eye patch, masks, etc.) could be combined with a hat. I don't think that's possible right now - and what's an eye patch without a pirate hat? Or a Monocle without a top hat?
