Feature Request: Pin / Highlight / Exclude Messages in Chat

I would like a feature in ChatGPT that allows users to manage specific messages within a conversation more effectively.

Key ideas:

• Ability to pin or highlight important questions/answers so they stay easily visible during the chat.

• Option to select specific messages and mark them as “excluded” , so they are not considered in future responses.

• Ability to identify or tag key points within the same chat for better organization and reference.

Why this is useful:

• Helps keep long conversations organized

• Makes it easier to focus on important context

• Prevents outdated or irrelevant messages from influencing new responses

This would improve usability, especially for long or complex discussions.
