  We propose a series of features for the graphical user interface (GUI) of the
COmputational MOdule Integrator (COMODI) \cite{Synasc05a}\cite{COMODI}. In view
of the special requirements that a COMODI type of framework for scientific
computing imposes and inspiring from existing solutions that provide advanced
graphical visual programming environments, we identify those elements and
associated behaviors that will have to find their way into the first release of
COMODI.
