Worked on the zed-industries/zed repository to deliver durable Markdown workflow improvements by implementing persistence for Markdown preview tabs across sessions. This feature involved designing a new database table and integrating Rust’s SerializableItem trait to serialize and deserialize active previews, ensuring seamless restoration after workspace reloads or restarts. The approach aligned with existing patterns for ImageView and Editor, minimizing risk and maximizing code reuse. By focusing on backend development, database design, and persistence, the work reduced manual steps for users, improved workspace reliability, and supported continuity in markdown-driven documentation, while maintaining a controlled scope for future enhancements.
