I'm not sure what you mean by this. You can already insert new
expressions by using the context menu. (there are items for insert
before this expression and insert after).
Is this not sufficient for your use, or just not intuitive?

Cantor currently offers the possibility of inserting items with rich
text formatting. We do not offer any formatting
options in the command entries itself, mostly in order to not
interfere with the automatic syntax highlighting there.
Do people really need formatting in the commands/results they produce,
or is it sufficient if they can write annotated text in between

yes, we really have accumulated a lot of noise in the debug output. We
should clean that up a bit.
