I know ipython notebook has the %%latex magic, but I think it only
works for the "mathematical" part (such as $e^{i\pi}+1=0$) of LaTeX,
and not the "structural" part (commands like \title, \section,
\itemize, \ref, \cite, etc.), right?  By the way, the ability to hide
an input cell seems also needed here (not just for the code cells),
since it looks weird to display the LaTeX source just above the output
formulas.  I think treating a %%latex cell in the same way as a
markdown cell might be better looking.

What I essentially suggested is to use the full LaTeX as the markup
language for the notebook, to produce something like Knuth's tex.web;
can use \section, \subsection, etc. for the same purpose.  It might
feel like something similar to TeXmacs (though I don't use it), not in
the sense of the editor commands, but in the sense of user interface.
To be clear, I am not suggesting to write a new LaTeX compiler, but
just to use the preinstalled system one.

why I said it is "crazy"), since the compilation of LaTeX can be
pretty slow (and may need more than one run) in some cases.
