iJoomla has a Section module ("The Magazine Menu module shows a list of all Magazines and associated Issues configured in your database.") ... a   few Content Modules for past, current and upcoming articles ("Module that shows all the articles in the default edition.") ... so what about a Category Module that would show a list of all the Categories and Content for each Category for each issue? 

You could have it show in the central panel above your vertical and horizontal zones by using {mosloadposition XXX} in the description field of the Issue's General settings.

Has anyone done this and is willing to share their code?

Hmm, I guess I am confused.  I thought ...
Section = Issue and
Category = Content Category

That's how it seems to be in the iJoomla Article Manager.  Guess I STILL haven't got this figured out (smile).  I'll keep playing with it.

Thank you so much for your help.  I keep asking help of the community and I keep getting you, Ricardo ... I'm feeling guilty.  I'd be lost without ya!  Thanks!
