Cosmetic dice is a good idea but please don't encourage micro transactions in a $60 game. lets break the cycle.
I don't think Larian would put microtransactions in their game anyway.
Cosmetic dice is not needed, maybe ask someone to make a mod for that option?
Toggle helmet is a neccesity though.
As for changing the colour of my bear, I don't think he would appreciate being made vibrant colours O_o. I might have an angry bear on my hands.
