In February 2026, Michael Johnson focused on refining the UI theming for the zed-industries/zed repository, delivering a feature that aligned the One theme’s visual style with VSCode. He muted the invisible character color and reused the editor.line_number theming token, ensuring consistency across both Dark and Light variants without introducing new color tokens or impacting performance. His approach emphasized UI/UX design and front end development, working primarily with JSON to implement the changes. The work was scoped to the theme layer, maintaining code quality and minimizing surface area, and included clear documentation and release notes to explain the rationale and impact.
