Developed OpenType Feature language support for .fea files within the zed-industries/extensions repository, introducing a dedicated submodule to extend editor capabilities. This work enabled syntax highlighting and language support for OpenType font feature files, streamlining typography workflows and reducing manual editing errors. The implementation leveraged git for version control, submodules for modular architecture, and toml for configuration management. By collaborating on commit bc02945d837618ca252fc9a023789016085b96d8, the developer laid a technical foundation for future typography tooling enhancements, improving the design-to-code process and supporting more accurate, efficient editing of font features directly within the Zed editor environment.
