I hope this hasn't already been requested, but I'd love to see negative filtering on module functions. For example, I want to search for Attenuators that aren't Polarizers, so I don't get attenuverters in my searches.

If there's already a way to do that, I can't find it.

Not possible right now. Workaround:
If you search by function you can set the result search order to Number of Functions ascending. You will get the modules with a single function first, in your case modules that just act as attenuverters and nothing else.
