Indeed!

Yes, I noticed the first bit as well, and have since better understood how
families work - the attached patch should fix that. It looks for mutually
listed relays via both fingerprints and nicknames (in case the relays have the
named flag).

I hope I nailed it this time round.

Yeah, I'd like that too. I haven't worked on grouping yet but I'll look into it
soon.

It'd certainly make it quicker to filter out the relays one wants to take a
closer look at - if one is interested in the impact of families. And sure. It'd
certainly make the grouping business easier because there's a family-uid one
can easily group by :)

Best, Michael
