I guess a group is less about chatting (we have that) and more about a collection of related events/notes being associated with a subset of people we've decided we want to talk about them with. We usually start off with a little clique and copy-paste links in from Nostr, but direct Nostr embedding would be nice. And some way to mark events as belonging to that group (like calendars), maybe with a label. Maybe we just want better SimpleX-Nostr integration. But they tried that and said it couldn't work, right?
