In todays structure of the bot messages, there is always a head and a body.
What I would like to see is a possibility for a developer to use either the head without a body od a body without a head. In longer conversations with a bot, there is no benefit in repeating the head again and again. If he just could participate in the chat without being so overweighted with its large header, this would givea better chat visual UX. So if I let the head or body free, why not hide it from the UI?
