I recently bought my first paid membership, and I've joined a bunch of fellowships. I'm a happy camper overall, but there's one thing that irks me: the list of my fellowships always there in my sidebar. I'd love to have the option to remove them completely (or maybe have a show/hide link in the sidebar itself). Many of the fellowships have animated smilies in the names, which I find annoying and distracting (albeit not enough to leave the fellowships :) )

I think you could gain a lot by adding customization to the sidebar similar to the way we can customize the main page.
