I used to save articles so I can read them later when I have time. But I have one problem that I always forget which one I have read and on which page I stopped. I Wish I can find a way to mark these dates and pages. That would help. I hope you can add this suggestion to adobe reader next product.
This forum isn't the appropriate place for feature requests if you want Adobe to note and log the feature request. This is: https://www.adobe.com/cfusion/mmform/index.cfm?name=wishform Your request is a long standing request. For the moment, the easiest way to do this it to purchase the yet unreleased large Kindle 2 DX which will be able to read pdf files natively. It has no trouble keeping track where you are in hundreds of books simultaneously.
