It works but it is kluge. The reason I like Collections is to get all the clutter on the home down to as few pages as possible. Sorting by Collections lists the Collections first followed only by books not assigned to a Collection and finally the Archive. Sorting by Title you can make the Collections display first using his trick, but then you have hundreds of books cluttering up pages and pages of Home screens. Yuk. Amazon should add a bit more control to Collection sorting.
