Since RedHat modified the customer portal to include little widgets on the documentation download, it now takes forever to download the books one at a time. The widgets do not allow for easy canvasing to, for instance, download all of the PDF document types using a download manager. Also, because the document download page does not display a date of last update, one must download a document just to see if it has been updated since the last time it was accessed!
I did submit a case asking for a zip or tar file archive of all the PDF documents to facilitate downloading and a date of last update to be displayed by each book. RedHat says they are taking both suggestions under advisement to see if anyone else should express similar desires.
So.. Here's your chance to weigh in if the current product documentation portal is not working well for you...
