Hello, .... Thank you for leaving your feedback. I would like to address your comments as they seem to deviate somewhat from the intended direction of this course. From the beginning, this course was not designed to be a standalone Electron course; rather, it is a course that covers the process of building a real-world application based on React and integrating it with Electron. A course that only explains Electron in depth can be learned sufficiently through official documentation alone, and even if filmed as a course, it would span a maximum of 2 to 3 hours. If I were to film a 3-hour course using information that anyone can easily find, what student would find it appealing enough to purchase? That is why this course focuses on building a functional app in combination with React, rather than just explaining simple concepts. In Chapter 1, I informed you that Electron is based on web technologies. Following that, the curriculum was structured to step-by-step implement features such as integration with React, simultaneous execution via concurrently, and in the latter half of Chapter 11, functions utilizing IPC communication—including settings pages, always-on-top windows, and location-independent notification handling. Additionally, at the end of each chapter, we ran React and Electron together so that you could directly verify the actual GUI results. Furthermore, I clearly indicated through the course title, introductory video, and curriculum that this is a course on building a React-based timer app. I find myself questioning whether you reviewed this information before purchasing my course. I will take your opinions into consideration. Thank you.
