During September 2025, Li Houzhi developed a usability enhancement for the slidevjs/slidev repository, focusing on improving code snippet handling within presentations. He implemented a configurable copy button for code blocks in the Shiki Magic Move feature, allowing presenters to easily copy code snippets across all steps of a presentation. The solution was built using TypeScript and Vue.js, with careful attention to user settings and consistent behavior throughout the presentation flow. Li followed CI-friendly practices and adhered to project conventions, ensuring maintainability. This work addressed presenter efficiency by reducing friction when sharing live code, though no major bugs were addressed.
