I tried using Your Media Library one time and found it so utterly useless that I never went back to it. I tried deleting the dozens of foreign dictionaries that clutter my lists but that I will never use. It wouldn't delete them. They cannot be deleted from the Manage Your Kindle page either. Personally I'm inclined to think that Amazon Kindle developers and managers do NOT understand books, libraries, or even reading. They seem to be clueless, and my patience is nearly gone with them.

BTW, I've switched to my iPad Mini Retina as my main reader now and gifted my crappy PW2 to a friend. No more eInk readers for me. They are a waste of my money and my time.
