This is not strictly true, TeXmacs can ‘cycle' among similar environments,
e.g. section, subsection, … or theorem, proposition, lemma,… or itemize,
enumerate,…

It is true that currently there is no option to cycle, e.g. between theorem
and itemize, but I should say I never felt the need of this myself.

Maybe it would be useful to describe some usecases which illustrate exaclty
which functionalities one would like to add.

In principle TeXmacs can support any automated modification of the document,
actually you can program it yourself because it is among the things one can
customize via scheme without resorting to modify the code of TeXmacs.

However I think to implement what you suggest, i.e. a shift from section to
itemize for example, would be nontrivial since sections apriori (in TeXmacs
and in LaTeX) are not proper environment so it is not syntactically clear
where they end.

Can you give me an example on how LyX operate to convert section into
itemize? What is the extent of text which ends up in the itemize environment?
Sorry but I do not have it installed right now.

This does not seem complicated, but again one would first try to think if it
is a useful and consistent feature and how exactly it should operate. I do
not think blind imitation of LyX is what we have in mind for TeXmacs.

Some example of the kind of editing flows involved would be appreciated.
Again I see your point but I didn’t recall to had this needs and so I cannot
figure out what is the most common use case.

In any way. I agree with you.
