Editing long prompts is cumbersome when the input area can’t expand; many of us draft in an external editor and paste the text back. Keeping the default single-line view is fine, but please allow vertical resizing of the input field as needed.

This change would:
• Preserve the current UI
• Significantly improve readability and efficiency for long-prompt editing
• Increase overall product value by boosting user satisfaction and retention
