[Scenario]

He's saying that he wants it (ability to add a server to a client's favorites list from a server-side function) as a possibility in the future. Unfortunately, I have a feeling that this won't ever be implemented server-side. Perhaps via a client-side function, but it's almost unnecessary. You can just get the IP/hostname and add it like you do now.

If it was a server-side feature, every server would simply add their server to a client's favorites list...
