Behind the Project

This project represents a significant milestone for me as it was my first attempt at developing VS Code extensions and working with PDF processing libraries. It was an intensive learning journey focused on integrating complex webviews into a native environment and managing local file systems securely.

I am committed to continuing the development of this tool. If you find it useful, please feel free to leave a comment or show your support. Your feedback is highly appreciated!
