It would be nice to be able to rename a Chat notebook, delete cells created by the AI agent or add some .md cells. ---

Chats are designed to be a chronological history of your conversation with the agent rather than a mutable document. They are append-only notebooks by design. If you want to revise or edit your chat, we recommend clicking the Fork button in the top-right corner and converting your chat into a notebook. (Though, we may support branching histories of chats in the future, where you can effectively rewind to an earlier point to restart the conversation…) Thanks for the feedback! ---

Thanks Mike. Forking the chat (i.e. turning it into a notebook) is the way to go.
