During April 2026, Haoqian focused on stabilizing the user interface for the preset-io/superset repository, addressing a regression that affected data accuracy after chart deletions. By updating the ChartCard and ChartTable components using React and TypeScript, Haoqian ensured that the UI now refreshes in real time when a chart is deleted from the All section, immediately reflecting the current state and reducing user confusion. This targeted frontend work emphasized reliability and maintainability, with clear commit messages supporting traceability. Although no new features were added, Haoqian’s efforts improved data integrity and enhanced the overall user experience through careful testing and code quality.
