During October 2025, Ethan contributed to the zed-industries/zed repository by addressing a nuanced bug affecting manual reordering of worktree paths. He restored the previous PathList-based sorting logic, ensuring that developers could once again arrange worktree paths manually rather than relying on default alphabetical order. This adjustment improved consistency and predictability for users managing multiple worktrees. Ethan’s work involved algorithm design and Rust programming, with careful attention to backward compatibility and user experience. He documented the change in release notes and collaborated with co-author MrSubidubi, demonstrating a thoughtful approach to software development and a focus on reducing user friction.
