During March 2025, Trung Nguyen enhanced the YerongAI/Office-Tool repository by updating Vietnamese localization across the application’s user interface. Focusing on internationalization and resource management, Trung utilized XAML and XML to refine language resources and improve the accuracy and usability of Vietnamese translations. He also streamlined Vietnamese keyboard shortcuts, making workflows more accessible for native users. The work prioritized user experience and localization readiness, laying groundwork for broader language support. While no major bugs were addressed during this period, Trung’s contributions centered on feature development and usability improvements, demonstrating a focused approach to internationalization and localization within the project.
