I think it would be cool if you could see all of your albums front covers on the my collection page, where all the albums are listed. So that you could switch between the text-only list view and a view with the cover images shown.
To give you an idea what I'm after (maybe with a bit smaller images):

This is probably not a terribly useful feature, but I thought it might be nice and probably pretty easy to implement.
