They could do it this way, provided that inside the plugin (MuPad, 
Maxima, Octave,
gnuplot, etc.) exists some kind of markup that you can translate to the 
TeXmacs
markup language. If the plugin directly generates Postscript, then the 
only thing
you can do is insert the Postscript image into the document.

You can have a look at :

>>

The Appendix A contains an overview of the current graphical markup
that you can use for translating your graphics into TeXmacs markup,
and the Appendix B gives an example of a Scheme function that
generates a drawing.

We plan to add a feature of annotating an image (.ps, .gif, etc.)
using a superposition of the image and a graphics.

It can be used for such a purpose (you can actually use it now to make 
geometry,
or mathematical drawings), but for flow charts or for a more 
sophisticated editor
for geometry, we need to add more features.

Thanks for the pointer.

You are not the first one to do this remark. We need to think about
finding a way to change this.

We changed the keys just before the release : you must use '+' and '-' 
instead.

Yes, this one is not exactly a bug, but something that doesn't
work well, anyway. The current workaround for this is to move
the cursor with the Left/Right arrows until you reach the edge
of the text box, and then the next press on Left/Right will
move the cursor into the graphics area again...

Best, Henri
