This is what I was going to say, that we keep coming back to Circles like Google+. It was one of G+'s best features.
Having a single category for organizing your social connections sucks. I’d love to have some sick user list management system 🤩
Lists solves this for the most part , IMO. I keep wanting to make various friends lists to make it easier to keep up with people's notes.
So tools to help create, organize, and update lists would probably be one of the best things to see on a client, or at the very least step in the right direction.
There is a huge need for an amazing List management client. @JeffG seems to be on it. :)
