It's good so far; a few UX/UI issues need polishing, some more display options would be nice too.
The whole issue of community@instance is going to take some getting used to for people, and it's not clear how that's going to shake out in the long run. I'm not yet certain whether this will become my default space, but I'm willing to give it a go.
There should be a way to make meta-communities. I.e. I could group [email protected] and [email protected] and so forth so it shows as one large community when reading it.
It seems like the intended use-case for federated stuff like this is that all of FOO would be in one instance, even though it's accessible from any instance it still shows which instance it originates in. Which feels a little weird, some topics don't really have a overarching supertopic that it makes sense for them to belong to.
I don’t necessarily want only FOO@xyz. I want to make say my cars meta community so I can look at several grouped communities like simracing, F1, Indycar etc. the meta community would be my creation and only for me.
