I wish they would add this feature to the Kindle natively, so you can choose 1 or more covers associated to a book. When the Kindle is color it would look very cool to havea 'virtual bookshelf' with all of the covers.
There are as many as 15-20 covers out there for some books, from the various publishers over the years. For example checkout the Stephen King carrie covers found on a quick google search: http://images.google.com/images?um=1...0&social=false
Would love to be able to pick a few favorites and rotate them.
