...
with the gui internals willing to take the challenge and write a state object that saves the current state of all (including the somewhat newer) the gui objects ?
Ideally I think the feature should go into PD itself... have each object which is 'state-able' implement a method to export/import its state. This would be a binary chunk of data with known size, parsed out with sscanf or somesuch.
just an idea... (i.e. I'm not going to do it ;)
