Right. I also think rich-text widgets are more appropriate than general

Good point. I want to add another little one; we fiddled around with several
setups for a (Qt-based) python shell, and one problem was indentation. The
terminal's main author really wants the prompts to be left-aligned, but
output to be indented, so that you can immediately recognize the beginnings
of paragraphs. Let me sketch it:
>>> a = [1,2,3]
>>> print a
[1, 2, 3]
Traceback (most recent call last):
File "<stdin>", line 1, in ?
NameError: name 'foo' is not defined
>>> for i in range(3):
... b = i
That'd be another user story for a GUI (anybody cares to add it for me?).
Actually I don't care much about it, and there will probably be other means
to quickly differentiate between the different cells, but anyhow.
Oh, and another one:
One might want to have the output colored differently depending on whether it
came through stdout or stderr; e.g. red for errors/warnings.
