why does the primary field have to be displayed?
SS assigns some type of unique identifier behind the scenes, so if I can't determine a good title for the primary field, I could just leave it blank, and it would have no impact.
In the old-school databases I used to work with, the primary field was used to link to other tables. I assume that is true in SS, but I'm not sure.
When you create a new app...and link it to another created app.....is there some association between the primary field of the original app and the primary field of the newly created app?
