Description:
Currently, Dify does not provide a way to edit sent messages, unlike ChatGPT. This feature is useful for correcting typos, rephrasing questions, or refining prompts without needing to resend a new message.

Expected Behavior

• Users should be able to edit their last message.
• Upon editing, the response should be regenerated based on the new message.
• The chat history should reflect the updated message instead of creating a new entry.

Why This is Important

• Enhances usability by reducing the need for redundant messages.
• Helps users refine their prompts dynamically.
• Improves the overall user experience, similar to how ChatGPT handles message edits.

Additional Context

Many AI chat interfaces, including OpenAI's ChatGPT, allow users to edit their previous messages. Implementing a similar feature in Dify would make it more user-friendly and efficient.
