• Interactive Checklist: Track your progress with a dynamic task list including a visual progress bar.
• Markdown Export: Export your generated plans as .md files for project documentation.
• Seamless Integration: A dedicated tool window that aligns perfectly with the native IntelliJ look and feel.
