Nicknames and hair

I would love to see two things in the sims 4. Firstly a nickname or preferred name for sims. I know you can call them whatever you want but sometimes you like a name but equally like the nickname that goes with it. It would be nice to have their proper name and then a nickname or preferred name. 

Secondly, natural hair. I know the game will automatically give any babies a natural hair colour but it would be nice for all sims to have a 'natural hair' colour, then they could change as much as they like without any children being effected.
