I'm not liking the updated Add/Remove Items to collections feature because you now you have to scroll through the entire list of Cloud items to put a newly downloaded book that is on your PW2 into a collection. Once again, bad Amazon, bad...rolled up newspaper in hand.

ETA: You can select to sort by Recent, but it is still kludge to have no ability to turn off the display of all your Cloud items, especially if you have hundreds of Cloud items. I think Amazon really screwed the pooch here by cluttering up simple tasks by displaying dozens if not hundreds of Cloud items rather than just those that are on your PW2.
