During May 2026, contributed to the 2dust/v2rayN repository by delivering a feature focused on refining the user interface and improving maintainability. The work centered on enhancing the OptionSettingWindow by binding combo box selections directly to display text rather than underlying values, which clarified data representation and streamlined user interaction. This approach reduced the need for additional mapping logic and minimized edge-case handling, resulting in a more intuitive settings experience. The implementation leveraged WPF and C# with an emphasis on robust data binding techniques, and maintained strong traceability by explicitly referencing related issues in commit messages throughout the development process.
