Request: Messaging in Manifold - Collection Announcements, etc

Would love to have a more robust communication system directly in Manifold.
Right now there’s a wallet messaging app by yungwknd & ambr0sia but it’s only a single message/recipient at a time.

I’d like the ability to send out announcement messages to everyone in a collection (or be able to make groups by metadata traits, or a manual list of addresses).

This would help keep important information more accessible and efficient (especially for interactive collections with special token mechanics or events) - rather than relying on Twitter/Discord.

Is there anything similar already? Or anything being worked on in that regard? Thanks!
