Configuration script for kali linux

Hi, I want a script to configure Kali Linux. As I haven't found any I will write down what I want it to do and I'll try to do what I can and I'll ask if I get stuck. If you know of a configuration script that does what I want please let me know.
- Prompt to create a new non-root user.
- Change key repeat speed.
- Install dotfiles configuration for both root and non root. Better yet make a global installation so if I add a user later will have the same vim configuration.
- Install a theme so it doesn't appear I'm using kali linux. I really like this themes which you can search in youtube:
Best theme for kali linux || Huge Customization of kali linux - YouTube
Custom Kali Linux KDE Ghost Theme!
How to make Kali Linux look like Mac
Kali Linux 2016.2 with Mac OS X Theme

- [Done] Check if running in a virtual machine and install guest additions, (dkms kernel too?).
- [Done] Change settings like blocking screen.

I'll have the script here.

Hey there :)

OK, with the risk of posing a stupid question. Why as a post install script ?
Why not simply make a custom Kali to begin with.

Adding an ordinary user, setting themes, installing software and so on, is sooo much easier done with a custom Iso.
I know it might not be as flexible, but for a more flexible install (i.e. diffrent machines), i'm thinking tasksel scripting coupled with the standard installer.

just my thought..
