I'm using a new widget area right now to add a small logo-ish image to the top of some of our category pages, such as the typewriter here: http://larchmontgazette.com/category/news/ and the photo of our Career Doctor, along with a link to her question form, here: http://larchmontgazette.com/category/careerdoctor/.
It would be great if there were a theme option to allow this, without having to create new widget areas.
Just hopin'.....
