Thanks for the reminder.  The list is indeed somewhat long,
so it would take some time to write a converter.
But it would make sense if someone has the time.

Of course, there is no TeX/LaTeX "source code" when you use TeXmacs,
so this would not make sense.

But after doing 'Tools -> Miscellaneous -> Export selections as -> LaTeX',
you can achieve the same effect without even having to switch to a source pane.
So this actually even seems a bit better than LyX, but maybe I am missing 
something.

But there remains the plain TeX issue.  Please let us know of possible
problems that you might have with the LaTeX code that we are currently 
generating.
I guess that there should be few differences between TeX and LaTeX when
it comes to basic formulas.  Maybe some of the symbols that come from
special packages may cause problems with plain TeX?
