Whisker Menu (Move an Icon?)

[Xorcist]

I haven't had much trouble installing applications or adding them to the desktop, etc. However today I installed the gnome-disk-utility, and it put a "Disks" icon under Accessories, I wanted to move it under System, and the best I could do was create a new item and disable the old one, no idea how to relocate an icon.

I also wasn't able to find where Whisker stores it's items (I'm assuming they are physical files somewhere on the disk). I know after installing gnome-disk-utility it put an entry in /usr/share/applications/ but I dont know how that relates to the Whisker menu.

Can anyone help me out a little.
