UPDATE
It has been called to my attention that this hack was already released by N9ne
HERE. While the hacks are slightly different, they are basically the same thing, which N9ne's hack being even more asthetically laid out. Therefore I have removed the attachment from this thread as I do not wish to disrespect anyone.

I do apologize and drats for releasing something that's been released. D'oh!

This is a very simple hack that may be useful for some and may not for others. For those of you who find this useful - yay!
What does this do?
This hack will add another column to the "modify usergroup" screen in the Admin Control Panel to easily identify each usergroup's ID number.
Why would this be useful?
If you're like me you don't have every usergroupid memorized...yet.

Instead of copy'n'pasting the "edit" link (or hover if the url is short enough), this will easily display the usergroupids.
This is my first real hack, if this can be called that. Please be gentle and I will try to provide support as best I can. If you find bugs within, let me know so I can update! Thanks again!

Enjoy!
