Hi all,
Many thanks for those advices!

I am new to org-mode but, is there a reason why #+BEGIN_proof #+END_proof
and other org-latex-special-block are treated as block ?
I mean; those #+... aim, as far as I understand, to give tips to org-export
for prettier exports but nothing else (between those #+... you still need
to write in org). I highlight that org-latex-special-block have nothing to
do (in my point of view) with #+BEGIN_latex / #+END_latex that allow a user
to insert some LaTeX within the document (e.g. Tikz pictures).
Therefore, it might a great idea to take #+BEGIN_proof & co into account
only when it comes to export the document. The proofs/definitions/theorems
will no longer be considered as block, and fast fontification may follow :)

What do you think of this ?

Best,
Leo
