Developed and integrated the Aurora Theme, a new dark theme inspired by northern lights, into the zed-industries/extensions repository. The work focused on enhancing visual customization by introducing the theme as a modular submodule, requiring updates to both .gitmodules and extensions.toml configuration files. This approach established a foundation for future modular theme additions within the platform. The implementation leveraged UI/UX design principles and front end development skills, with configuration managed using TOML. The contribution was documented in commit 80ee13ad4cd929f3f352c6be8ca49aa0617c957f, reflecting a targeted, well-scoped feature addition over the course of one month.
