Hermes,
in my view, the creation of fields, forms and the "wiring" of elements to build functionality
will never and should not be in the hands of end users.
BUT - if I understand correctly, that's not what you mean. Your request is about layout and styling of pages, right?
I had a similar idea, (no comments yet)
It is about using pieces of content information more flexibly on the content page,
in particular: placing fields in the fulltext area.

Right now, I see all SEBLOD users (devs and end-users) limited to
the predefined layout of information that is given by the content type and its template.
A field's position can only be defined in the content type editor and once it is set, it's there to stay in that place of the layout.
There is no way to make use of the very flexible SEBLOD "field / layout system" in the article editor.
All you can do right now is to fill in the form and stick with the predefined content layout.
... Unless there was an oversight on my part :)
I think it is time for a feature request in the tracker.
