Wait... how are we talking about all of these other ideas and this one hasn't been implemented yet. it's the most standard feature on any messaging app. When sending a group message there should be an option to turn on and off the ability to have the members of the group respond to me directly or to everyone in the group. And I should be able to respond to a specific user directly without everyone in the group getting the message. There have been times I've sent out a group message and the response which wasn't applicable to everyone in the group kept being shared to all. it became annoying.
