I agree with the editor idea, i made my character with the idea that i might not be able to change him. As a result i played the safe side and didn't add any scars. now after playing for a while i would like to, and i am sure something will come along eventually.
but for all those against the idea of some character editor, I ask why does it bother you so much? if you make your character perfectly, then why does it matter to you if the option is made for everyone else who might have unfavorable qualities to edit their characters? like that annoying person at work, its up to your discretion to acknowledge it or not.
