Developed Dimsum, a minimalist menu bar utility for the jaywcjlove/awesome-mac repository, designed to enhance window management on macOS by dimming inactive windows and highlighting the focused one. The feature aimed to improve multitasking usability by providing a subtle, non-intrusive visual cue that reduces cognitive load. The implementation demonstrated skills in UI/UX design and documentation, with careful attention to window state handling and user experience polish. The work was scoped to a single, low-risk pull request, reflecting disciplined commit practices. Markdown was used for documentation, ensuring clarity and maintainability. No major bugs were addressed during this development period.
