gEDA has no such strong association. It's a product of the way you *use* gEDA. > That's just... wrong.

When first drawing the circuit that needs a low noise opamp, copy one of the opamp symbol files into your project symbol directory under the name "low_noise_opamp.sym". Place that. As its pin numbers, attributes, etc. become clear, edit it ("Hs") to suit. Or replace the symbol file with something else. gEDA uses a powerful, hyper flexible association mechanism that other packages can't match: your computer's file system.
