dsh-chat-index

When a dsh web conversation stretches into dozens or even hundreds of turns, scrolling back to locate one particular question becomes tedious, and the headache multiplies the moment you start jumping between branch or subagent sessions. dsh-chat-index is a lightweight, purely front-end plugin for the DeepSeek Harness Web UI that overlays a visual question map on every session, turning endless scrolling into a single click.

Concretely, a thin dot rail appears on the right edge of the chat. Each user question gets one dot, spaced in true time-proportional order (earliest at the top, most recent at the bottom). Clicking a dot scrolls the chat to that message with a brief highlight; dragging the rail lets you sweep quickly, and a small summary tooltip fades in beside the pointer. A persistent toggle in the title bar or at the base of the rail opens a chain panel that lists every question with its summary and timestamp. Branch and subagent sessions render as child subtrees under the main conversation node; clicking a child node switches to that session first, then locates and highlights the target message. In empty sessions the rail stays hidden but the panel remains accessible with a placeholder notice. Because the plugin is entirely client-side, it requires no backend changes and takes effect the moment you refresh the page.

It is built for anyone who runs long, multi-turn conversations in dsh web, especially those who rely heavily on subagent or branch workflows and are tired of lost-in-scroll searches. The combination of a time-proportional dot rail, an expandable chain panel, and first-class branch-session subtrees sets it apart from other navigation helpers.
