I don't think that this is the task of FriCAS. Where would you break a
TeX-Equation? The only think that FriCAS could do is to insert
breakpoints suggestions so that the latex processor would have a better
chance to break in the right place. That FriCAS would compute the width
of tex boxes is not the right thing in my opinion.

No. I think the reason is that my package is GPL3 and I have no
intention to change it. It can happily live as a contributed extension
in source form.

And right so. ;-)

Yes. And there are some bugfixes in my package.

Correct. And I also think that this is a hard thing to do. Not that you
would probably prefer
(long formula) / (other formula)
over
\frac{long formula}{other formula}
in certain situation. The same happens for \sqrt{long formula}. In the
\sqrt case one would probably try to break the formula inside so that it
fits the width of a page. But then imagine you have
\sqrt{long} + \sqrt{\frac{long}{long}}
How would you automatically distribute the width that each summand gets?
Maybe with properly breaking inside \sqrt the whole sum fits in one
line. I wouldn't want to decide for the user's taste. I don't really
think that this is a computer algebra task.
