I'm moving the discussion to the texmacs-dev mailing list.

This looks like the bug #36233 in the TeXmacs bugzilla. Even simpler, when 
I say

1;2;

at the (%i1) prompt, I only see

(%o1) 1

but not

(%o2) 2

though both lines are sent from maxima to TeXmacs. I really hope this bug 
will be fixed soon.

It is perfectly possible to have multi-line input in the TeXmacs-maxima 
interface. At the maxima prompt, say

(%i1) 1;<shift-enter>
      2;<enter>

You will have 1; in the first line, and 2; in the second one; both are 
sent to maxima by <enter>. By the way, in this case I see both output 
line, not just the first one. Observing the bytes sent by maxima to 
TeXmacs shows that they are exactly the same in both cases. So, it is this 
time-dependent bug - in the first case the line number 2 is ignored, while 
in the second case it is displayed.

Bug #36233

It's interesting that many people want this. When I say

plot3d(f(x,y),[x,-a,a],[y,-b,b])

in TeXmacs, I get a gnuplot window, in which I can rotate the plot with 
my mouse, export it to various formats, etc. It is a live object. Inlining 
it it the TeXmacs window would make this object dead. I think the first 
way is much better.

It is certainly possible to inline maxima plots. It somebody wants to 
implement this, go ahead. As long as this remains an option which I can 
switch off.
