Feature Request: Message Management Tools

In long, information-heavy conversations, it’s difficult to quickly find specific responses when scrolling back. I’d love to see a few features to make this easier:
• Collapsible responses: Allow longer responses to be minimized with a short summary or preview line, so users can expand only what they need to review.
• Tagging or pinning system: Let users mark specific responses (or parts of them) as important, with the ability to easily jump back to those points later.
• Highlighting: A way to highlight key parts of ChatGPT’s responses would make reviewing important information much faster.

These additions would greatly improve usability for research-heavy or technical discussions.
Thanks for considering!
