Worked on MaaAssistantArknights to deliver a localization-driven user experience improvement focused on multi-instance usage. Addressed the single-instance limitation by updating XAML-based localization strings and enhancing user guidance, instructing users to copy the application to separate directories and configure distinct ADB and connection addresses. This internationalization effort improved the clarity and consistency of user-facing messages across multiple languages, reducing confusion and potential support issues. The work strengthened product scalability by enabling power users to operate multiple instances more effectively. All changes were implemented in the MaaAssistantArknights/MaaAssistantArknights repository, emphasizing internationalization and localization best practices throughout the development process.
