During January 2025, Onno focused on enhancing the documentation for the copy-on-select feature in the ghostty-org/ghostty repository. By clarifying clipboard behavior across Windows, macOS, and Linux, Onno addressed potential ambiguities that could impact onboarding and support processes. The work involved careful revision of technical documentation using Zig and a strong understanding of cross-platform clipboard management. Although the contribution was documentation-only, it demonstrated attention to detail and a commitment to reducing support overhead. The changes maintained a clean commit history and improved the reliability of user-facing information, ensuring that developers and users could better understand feature behavior across environments.
