I have just released another version of SPD, more info here:
http://groups.google.com/group/spd-dev/browse_thread/thread/f6e9b20ddf4c262e
I am writing here to ask for thorough testing and feedback. :)
Also, if you look at the front page:
http://code.google.com/p/spdproject/
there is a simple demo, that uses most of those preinstalled packages
(python, numpy, scipy and matplotlib). What I love about it is that
just couple months ago, we were exchanging that simple demo script in
an email conversation with Robert and Jirka, and now we can play with
it in the notebook and/or easy to install SPD.
