I have a huge number of contacts. If there is absolutely no better way to organize them than a "flat file" list of groups, I may be forced to export each card individually just so I can have them in a directory structure.
The things I love about Apple Contacts are:
- Integration with Mail.app.
- Integration with Alfred PowerPack.
- Pretty UI.
So this is really a two part question.
- Is there any way to have hierarchically nested groups in Contacts.app? And,
- If not, is there any other application I could use that would give me this functionality without sacrificing other usability too much?
I have one possible not-so-great workaround myself, which I will post as a self-answer. I'm hoping someone else has something better.
P.S.: Using El Capitan 10.11.6.
