Worked on the AFFiNE repository to enhance reliability and user experience in data presentation features. Addressed a keyboard shortcut issue by refining Alt+Meta key handling, ensuring that locale-specific input characters are correctly distinguished from actual shortcuts, which improved cross-locale usability. Developed deterministic table header sorting logic using TypeScript, stabilizing row and column order when values are tied and reducing layout shifts during edits or refreshes. These improvements in front end development and data visualization contributed to more predictable behavior and smoother workflows, increasing user confidence in the application’s data rendering and interaction consistency across different environments and input scenarios.
