I apologize upfront if this is request in the wrong place. I have many users requesting / wishing this feature existed. The request is that when a user sends a broadcast message that the message sent is then copied into / displayed in each of the recipient's chat window on the sender's end. The recipients see the message of course, but the sender does not. Sometimes it is just helpful to see what is sent, without asking someone to copy/paste and send it back to the sender.
Thank you for your consideration.
