Full access to the system's files is easy to obtain with an administrator's account provided you know the trick for doing so (that's how I modified my version), but I'm hesitant to release the details on how to do it because I don't know your intentions. Sorry.
My intentions are if I have a program that need to modify or access a file that needs root ass my program can enable to have access to root. I don't want to have to have root from the start only when needed.
