I don't think it's your mental state. Those tools are clunky.
Have you looked at Ivica's [preset_hub] in Pd-l2ork? You simply name
the [preset_hub],
and all the [preset_node] objects with the same name on that canvas or a
child of it
(including abstractions) work together. No need to use dollarsign
arguments at all.
All state is saved with the patch and adding/removing nodes works
seamlessly, even with
infinite undo.
His preset system even makes an automatic, hidden connection back into
the [preset_node]
so you don't get crossed wires.
