Worked on the 2dust/v2rayN desktop application, focusing on enhancing user experience and interface consistency using Avalonia and C#. Addressed a startup window positioning issue by applying saved width and height during the initialization phase, ensuring the main window centers correctly before the startup location logic executes. Improved dialog behavior by disabling the minimize button on specific child windows, which prevents independent minimization and creates a more predictable interface. These changes reduced user confusion and support requests, reflecting a thoughtful approach to desktop development. The work demonstrated attention to detail in UI behavior and reliability within a modern C# desktop environment.
