Update conversation title in sidebar also when using a persona

[slobentanzer]

The original "New Conversation" has a feature that generates a conversation topic and sets the title of the conversation in the sidebar to this topic, making it easier to find a previous conversation. If we select a persona, the conversation title will remain the persona name. Can we adjust this and make every conversation behave like the former, i.e., use the generated title? @fengsh27
