Less like Chat, more like Threads
People don't really use the reply in Chat very much. So when everyone is creating a new conversation there are a ton of UI elements all over the place making the whole window very cluttered.
I'd suggest adding a Subject Line to the conversation so that there is a quick summary though for the thread.
Then it would be nice to be able to click into that thread so you don't see all of the other chats.
We actually do have a subject line.
If you click the little pencil in your text field, the text field will expand and you can write a title for your message.
Now, that we know that an realize that everyone in the Team was using the Channel like a message board, we're unable to go back and delete the unwanted messages. We need to be able to clean up by deleting conversations.
