I just used my feedback forum to request the addition of a last.fm album art widget to the availible sidebar widgets in the presentation section. For those of you that dont know, last.fm is a service that records and generated reports and feeds about the music you listen to. You can see a sample of the plugin at work at http://dirkie.nu/category/widgets/ .
For those of you who think this would be a good idea, use your feedback forum to do the same. its on the top right corner of your main user page.
