During February 2026, Kin Chong Wong developed an Enhanced Stepper Popover System with Recursive Hoverover for the source-academy/frontend repository. This feature introduced nested popovers to the stepper component, allowing contextual display of function definitions and reducing context-switching for developers. Kin Chong Wong reworked the rendering logic and refined SCSS-based styling to address popover depth and formatting challenges, resulting in a cleaner, more scalable user interface. The implementation required updates to supporting components such as SideContentSubstVisualizer.tsx to ensure compatibility. Using React and TypeScript, Kin Chong Wong delivered a robust, maintainable solution with no regressions observed in related areas.
