Similar to how editors like VSCode let you jump to parent items in a hierarchy, it would be helpful if ChatGPT allowed users to navigate the conversation in a structured way. Since questions, answers, and follow-ups create a hierarchy, having options to collapse answers and easily move through different parts of the conversation would improve clarity.
Also, the ability to edit previous questions to create alternative threads, along with better tools to visualize and navigate these branches, would make long or complex chats easier to manage.
