TypingMind has made it very convenient to switch models part way through a chat session. However, it's exceedingly difficult to identify where such model switches took place. I think the most useful solution to this is to use the LLM's icon in the chat for the AI output, rather than the currect practice of using the TypingMind icon. This way, it is always clear and easy to identify which LLM produced any given AI output in the chats.
