So in Pokemon Go and Harry Potter, you can add friends. In Ingress you can't.
I feel this feature should be added. Here's why:
Privacy. A lot of agents set their scanner stats to private. Whatever their reason, I feel that we should be able to add friends who then can view our scanner stats as if they were open.
There might be other useful additions to having in-game friends, but this is something I've been thinking about.
