First of all, it’s really awesome to see that finally someone from the Chat Dev Team itself is actively reading and commenting on issues/suggestions from us!! That’s a huge step towards a better chat experience for everyone.
Regarding group chat, it was/is an interesting new feature but it lacks lots of functionality. Actually, like most of it was already mentioned, so there’s no need to repeat it.
In my opinion, that’s the best use case for it and should exist for every channel as a second tab and a subs-only (with/without mods as an option?) as a third tab for channels with subscription program.
This way, the mod chat can also be used to configurate bots through chat
