I really can't see all the problems/complaints people are having with ADE page numbers... these synthetic page numbers are the only useful way of having page numbers at all with something as dynamic as a completely user-formattable ebook combined with a variety of ereader screen sizes. If page numbers would depend on ebook formatting, you could put away with page numbers as well. Page numbers are not some decoration, but a tool to find passages in a book, and ADE page numbers provide that, on every variety of ereader or e-reading app, and for every single ebook on this planet.

I like ADE page numbers! They are useful and practical. They are universal. They work, always.
