Idea for XCOS improvement

[xwang1976 at email.it]

Hi to all,
I'm a Simulink/Matlab user and I would like to use XCOS as an open 
source alternative.
The most important thing that keep me from using it is the lack of the 
possibility to name superblocks inputs and outputs port as it is 
possible to do in Simulink and Matrixx.
This feature is very useful IMHO when the simulated model begins to grow 
because it clarifies the IO interfaces of the blocks which constitute 
the model and permit to use a top-down approach with nested superblocks.
Is there any plan to implements such a feature?
Thank you,
Xwang
