gconf-editor

gconf-editor provides you a little geeky way to tweak Ubuntu configurations. It reads the XML configurations in directory ~/.gconf and /usr/share/gconf, and presents these configurations in a human-readable way. But if you think gconf-editor is not geeky enough, you can always directly modify the files in those directories.

Have fun.
