CWP Panel Customization - Github project

Need to edit/customize CWP web panel in order to create webmail accounts for exclusive domains. Just like creating a Hotmail account. I'm not talking about creating sub accounts, in a web hosting account. Editions must be made in github.com and will also need to edit update function in the codes of this open source web panel.
