Writer's Tools is an all-around tool designed to help OpenOffice.org users to perform a wide range of tasks. It makes easier to backup documents, look up and translate words and phrases, manage text snippets, and keep tabs on document statistics.
i can't remember why i didn't warm to this office suite when i first tried it. openoffice remains a little fiddly through X11 on the mac (esp copy, paste and drag) - time to switch i think.
