Dear list,
First of all i'd like to say that i'm very impressed
by the potential of data structures in Pd. I've always
kind of ignored this feature and it's a pity because
it's really worth diving into it.
That being said I think that help and example patches
are far from sufficient for beginners, and if it wasn't
for Chris McCormick's s-abstractions I would have been
able to really figure out how to use them (stuff like
how to make an entire polygon draggable, how to use GOP
with proper scaling, etc.).
