In March 2025, Martin Hettiger developed the Floating Terminal Windows (Always on Top) feature for the ghostty-org/ghostty repository, enabling terminal windows on macOS to remain visible above other applications. He implemented this functionality using Swift and the Cocoa Framework, integrating a user interface toggle and ensuring user preferences persist across sessions. The feature addressed multitasking challenges by reducing context-switching for developers who require constant terminal access during complex workflows. Martin focused on user interface design and macOS development best practices, delivering a targeted enhancement that improved productivity without introducing new bugs, reflecting a focused and well-executed engineering effort.
