This is a great addition. I was so confused when I thought, “wow, a dynamic example image showing my username”, and then realizing it was just a screenshot of my username. 
I love how quickly this chat feature is growing–I can’t wait until the right time to add it to our community. As much as I love Discord, from our business use case, I really don’t want to have another platform to manage and to fragment my users into.
A nice feature to have would be to select one or more chat messages and break them off into a topic.
