There is no character viewer, there never really can be one, there's hundreds of different appearance modifiers in the game. Cait's always going to be a blue-eyed pink-haired cat girl, but the PC can be a black-haired cow-girl or a blue-haired salamander or a blonde human with demon horns and 6 tits, black eyes and a fox tail. It's completely unworkable to have a character viewer outside of your own mind.
