It was the equivalent of PowerTools(/Tweak/XP Toy? possibly had another name) for Windows XP in that it made many Gnome & Compiz tweaks one-click options, which given Ubuntu's easy-to-use focus went down well. Things like displaying certain icons on the desktop (which I know in Windows used to require a registry setting without a tweak tool), or the contents of your home folder on your desktop.
