During a two-month period, Fangoritospade developed and maintained the Mangoes Theme for the zed-industries/extensions repository, focusing on UI/UX design and front end development. The work involved introducing a dark tropical-night color palette as a submodule, updating extension metadata using TOML, and ensuring compliance with open-source licensing. Fangoritospade emphasized visual accessibility and maintainability, architecting the theme for future scalability. Subsequent updates stabilized UI behavior and addressed known issues, reducing support overhead and improving user experience. Throughout, Fangoritospade demonstrated disciplined version control with Git and collaborative release practices, delivering a robust, visually consistent theme that supports ongoing extension development.
