title_body: Collections Mangement of Kindle Paperwhite 3
upvoted_answer: An alternative, which at least gets round "kindle is slow" is to use the Kindle app, on e.g. Android phone or tablet, if you have one, to manage your collections.
  
  The Android app does support the new-style "cloud collections", as used by the PW, Voyage, etc.
  
  The advantage here is that it is much more responsive, both in screen display and touchscreen behaviour and, with a tablet, larger with easier to see covers. It supports a multi-select mode, where you can select many titles at once, to add to a Collection.
  
  That's what I do, anyway: use the Kindle device to read, and the Android app to manage.
