Just an option for group owners to toggle permissions for the various roles to talk in the groupchannels would make a lot of people happy.
There are a lot of update groups from various content creators, which is a brilliant idea, but the usefulnes is often negated by people thinking it's a great place to spam their own products. There's other groups and places for that, it doesn't only undermine the bussiness of the groupowner, but I doubt many people are actually waiting for continuous spam in their chat. And no, I don't even have a bussiness (yet), but I do know I left a good number of update groups already because of this. Knowing I now miss out on the latest creations of some very good designers, but just a normal talk with a few friends becomes a nightmare when some %@^$^!@ starts spamming an update channel again, cluttering up my complete chat and annoying me with those annoying pinging messages.
