Sure it *could*. It doesn't. Right now I find it puzzling at best.

Still window handling feels clumsy in XEmacs. Developing
Lisp programs using XEmacs as an editor connected to a Common
Lisp is not my favorite one. I know, a lot of people see it
differently. But in my experience some Lisp IDEs are vastly easier to
use and better looking. From my personal UI point of view XEmacs/Emacs
are (to say it mildly) not very advanced.
In MCL for example the editors and listeners are different windows.
Executing code from an editor runs the code in the
top most listener. That's where the output goes. Handy.
And the Lisp UI works like the rest on that machine: adheres
to the platform standards and is simple to use.
In LispWorks for Windows running code from an editor
actually uses a kind of typeout window. Each editor has
an output buffer and you can get to it by clicking on a tab.
It is not that bad, but I like to see my code and it's output at the
same time. Additionally you can link windows (clicking on an object
in one window (say, a class grapher) will result in an update
of a linked window (say, an inspector)), which I have seen
first in the Apple Dylan IDE.
On the Symbolics I have some options: 1) press the suspend key and
a typeout window appears on top of your editor window. This is
a listener and the code below that is active - it is mouse sensitive
according to your input state of ypur typeout window. 2) You can get
a permanent effect of the above by creating non-overlapping
editor and listener windows.
>in addition, the advantage of emacs is that all the source code is freely
As a Emacs user I have source. As a Symbolics user I have source, too.
Makes not much difference in practice. If you need an extension
you either develop it yourself, ask somebody else or ask
the people who created it. Makes not much difference to me.

Even a bunch of "loosers" breaking the thing with "improvements". Sorry.

Symbolics was up last time I looked - two weeks ago.

Reality is more complicated than that, IMHO.
