More restrictive permissions for "other" admins

[Velocd]

I think assigning another admin to a forum is a great idea, if its somebody you can really really trust, because they can help you work on the forums and add-hacks, etc. but my only problem is when you do assign an admin, there are no permissions against what he can or can't do in the admin cp. Is there a hack out there already that assigns permissions to a second admin of what he can/can't do in the admin cp? For example, I really don't want my admin to have access to the vbulletin options page, or the users lists, and restrictive options too. Like I don't want my admin to be able to drop templates or template sets, to drop styles, or to drop forums, stuff like that. You could set these permissions by first creating a new usergroup for the admin, and in the modifications page allow them access to the admin cp. But in the same page in the section where the option "allow access to the admin cp' is there could be other permissions like the ones I mentioned above. This would be a great hack if not already made
