Definetly. IMO subpatches in a modular synth are as important as "Undo" in
a text editor. They not only can hide things, they make modular and object
oriented development with lots of re-use possible. In this regard it also
is crucial, that subpatches accept arguments like functions in most
programming languages (C, Python,...).

The newer versions of Pd (>0.35) have this nice invention of "graph on
parent" subpatches. This means, that GUI elements (sliders, knobs...) in
subpatches - but no cords - are shown in the surrounding, parent patch,
like a see-through patch. With this, one can build one-gui-per-module
GUIs, but it isn't enforced. Or, what I did in my sequencer abstractions
for Pd, one can build pure-GUI objects that don't actually have a lot of
module action inside.
