Really? Why?

And how is that not broken up into small parcels?
(side-note: a dialog can contain sub-dialogs, each subdialog showing
small pieces of information)

Really? That's very unflexible if you ask me. You see everything as
scripting. In fact, I see very little as scripting.

You should note that you lose a lot of C++'s power if you switch to

And just for fun, you can accomplish the above using save_dlg, very easy:

std::string headline(const your_struct & val) {
   return "Headline: " + val.m_title;

When creating the corresp. class, simply say:

add_corresp( &headline, ID_whatever_field);

Show me real examples where this makes sense. And let me repeat:
- the 1:1 is a current limitation
- you can work around it.

And more to the point, where do you do validation? I don't see it
anywhere in code.
