On the Nook or Kindle app on any of my Android devices or the corresponding PC apps from B&N and Amazon, with multiple books on either Nook or Kindle, the eReaders open up to the page I was last on for any given book whether a Nook book or a Kindle one. Obviously Adobe Acrobat Reader XI doesn't do this, nor does/would fully licensed Acrobat (which I also have) unless I specifically create (and re-create as I read a book) a bookmark. Any apps on the Store or otherwise that would do this? I read a lot of technical manuals (IBM Redbooks) for which this would be handy. Thanks in advance.
