During May 2026, Xingkai worked on the Lum1104/Understand-Anything repository, focusing on front end development with React and TypeScript. He implemented a dual-view dashboard toggle that allows users to switch between file-level and class-level graph views, reducing visual clutter and streamlining architectural analysis. His approach emphasized state management to ensure the function toggle persisted correctly across view changes, addressing reliability issues. Additionally, he improved usability by hiding non-applicable toolbars in certain domain views, resulting in a more consistent user experience. The work demonstrated thoughtful attention to performance, clarity of view semantics, and stability within a complex dashboard interface.
