During December 2025, contributed to the wavetermdev/waveterm repository by developing two user-focused features aimed at enhancing terminal usability and file preview functionality. Built a manual refresh mechanism for file previews, allowing users to reload content such as code, markdown, PDFs, images, and media without reopening the preview, using a refresh icon integrated into the UI. Also implemented keyboard shortcuts for efficient navigation through terminal output, supporting rapid movement to the top, bottom, or by pages. Leveraged React and TypeScript to ensure these features aligned with existing architectural patterns, emphasizing maintainability, testability, and a seamless user experience across the front end.
