Maybe, I was talking about the default.  (And I even don't know now how
to correct it, since LaTeX does not have a notion of a "section tag" -
so there's no obvious way to represent such an entity in it!)

Sorry, I did not get that idea.  We are not talking about
converting /different/ objects into /sections/, are we?

Agreed.

Well, in this particular case I can definitely live with what Org
gives.  (The fact that I don't use the exporter too often helps;).)
In other words: the status quo *is* (more or less) a "suitable
workaround", at least for me.

Hm, I did not understand this point:(.

My opinion (as a LaTeX user and hacker, if I may say so) is that LaTeX
exporter may be not optimal, but it is decent enough.  I agree that
it is a lot of work to make it better, and even then it's not enough,
since there is no "canonical" way to transform some Org-specific things
(like tags) to LaTeX syntax - so someone will be unhappy anyway...

What is important here (as I hinted previously) is the point of having
a LaTeX exporter: do we aim at pdf, not caring about the readability
and elegance of the (then intermediate) LaTeX file, or do we aim at a
good quality LaTeX file to do further (manual!) work on it, including
(but not limited to) "visual tuning".  I'm sure there are some people in
both camps, and satisfying all of them may be tricky.

Now that I think of it, writing a completely new LaTeX exporter might
actually be a lot of fun - I'm afraid, though, that I don't have enough
time for it now...
