dsh-session-nav

When using DeepSeek Harness Web GUI for multi-turn conversations, especially in lengthy sessions spanning dozens or even hundreds of rounds, users often struggle to quickly locate and review historical messages. Traditional scrolling is inefficient and lacks intuitive navigation. The dsh-session-nav plugin addresses this by providing a piano-key style navigation bar, where each user message is visualized as a key, offering an at-a-glance overview of the entire session structure. Hovering reveals a preview of that conversation turn, and clicking enables smooth jumps, significantly enhancing navigation efficiency. Built on the official DSH dual-side plugin mechanism, it operates without modifying the core code, supports full history data, and can display all user questions even in long sessions while intelligently syncing with real-time scroll positions. This plugin is ideal for all DeepSeek Harness users—especially developers, researchers, or everyday users who frequently handle long dialogues and need efficient history traversal—helping them focus more on the conversation content itself rather than cumbersome navigation tasks.
