Worked on the ghostty-org/ghostty repository to enhance macOS window management by stabilizing window restoration behavior. Addressed a persistent issue where window size and position were not accurately restored after closures or on first launch, aligning the application more closely with native AppKit state restoration. Refactored the window cascade logic into a centralized helper function, improving code maintainability and readability. Utilized Swift and object-oriented programming principles to ensure explicit coordinates were honored and state persisted correctly. These updates improved the user experience by preventing window misplacement and reducing the risk of future regressions, demonstrating a focus on incremental, maintainable delivery.
