I've been wondering for a while if there are plug-ins or add-ons to add filters to smart groups. The truth is that Apple does so many things right but with certain very specific things it's beyond me what they were thinking when they designed it. The smart groups is one of those things. It has so much potential but it's just begging to be made just a little more powerful. I feel so restricted by the limited filters it offers that there must be a plug-in out there somewhere for it, I just haven't been able to find one. (Why can't I for example select all the companies in my address book, not the ones with "Company" set, I want to be able to select all the cards with the company check box set, so that it weeds out all the actual people business cards with companies set for them. Or why is it that street address is the only [and most important] part of the address that I can't filter by? How come I can't have a smart group that shows me which cards have no street address set but do have a phone number set so I can see which ones I can use Google Maps to reverse lookup the phone numbers for addresses. And why can't I filter by whether the contact has only the home phone or mobile phone entered.) There are so many more examples of just nagging lackings in functionality here. There has to be something out there. Anyone seen anything?
