It's a far bigger task than it sounds red1, to be able to create some sort of "auto-modder" would really require a rewrite of snitz to allow for some form of versioning and code comparison to take place, definately not a small task.
I agree it would be a really nice feature to incorporate, but its just not one thats going to materialise anytime soon. And hey if everyone could automatically apply MOD's without any help then heck this forum would get a real lonely place
