When we set the "display" setting in form designer, who are we displaying to?
Using Jamroom
Any ap or tool that is created is going to be a limitation on what exists now. What exists now is no-limitations on how you present the data. The best an interface to replace that could hope to do is offer some set of pre-set designs to be chosen from.
I can't see how that extends anything, it limits it. I can see that if you
really really really don't want to ever look at code, that that could seam like a better option.
But before resigning yourself to that point of view, take a quick look over this page, it has 2 methods to alter existing templates so you can add in these changes without an interface.

I think you'll find the biggest decision comes from deciding where you want your output to be placed.
