Hello Mango 😊 Thank you so much for leaving such a valuable review. 🙏 I truly appreciate you honestly sharing that it felt a bit different from the direction you had in mind. While this course was designed to go beyond simply creating features and help you understand code structure and flow for refactoring, as you mentioned, I will continue to improve it so that future courses include not just feature explanations but also principles and improvement processes. In the next course, I will focus more on "why we should implement it this way" rather than "how to implement it," and I will prepare content that shows the refactoring process directly so you can develop design sense as well. Also, if you have any points that felt lacking while taking the course or additional topics you'd like to see, please feel free to share them anytime. Each piece of feedback is a great help in developing the next course in a better direction. If you need help with anything in the future, I will always be ready to assist you wholeheartedly. I hope we can continue to communicate and create better learning experiences together. Thank you once again from the bottom of my heart, and have a wonderful day today 🌿 There's also an open chat room for communication with students, so please drop by when you have time. 👉 https://open.kakao.com/o/gC10Fnoh
