Hugo Gouveia contributed a focused documentation update to the ghostty-org/ghostty repository, clarifying the behavior of the background-opacity setting on macOS. He specified that changes to this setting require an application restart to take effect, addressing a common source of user confusion and aligning documentation with actual cross-platform behavior. Working exclusively in Zig and leveraging his documentation skills, Hugo ensured that the update was concise, traceable, and easy to follow, with all changes captured in a single commit. This work improved onboarding and support processes by making platform-specific nuances explicit, demonstrating careful attention to user experience and documentation hygiene.
