dsh-user-message-navigation

What kills you in a long, multi-turn conversation is not a wrong answer but not remembering which prompt started which approach. You scroll down, scroll back up, lose your place again. dsh-user-message-navigation renders a compact vertical minimap on the left side of the chat pane, compressing every user message into an ordered tick mark so the full prompt history is visible at a glance and any round is one click away.

Interaction is straightforward: click a mark to jump to that message, drag along the track to sweep through rounds continuously, or step through with the keyboard. Short hops use smooth scrolling; long jumps and drags snap into place instantly. Hovering reveals a text preview of the corresponding prompt, and the target message is highlighted in the active DSH theme colour while respecting the system reduce-motion preference. When fewer than four user messages are present, the track hides itself to keep short exchanges clean.

This plugin is built for engineers who iterate with DeepSeek Harness through multi-round debugging, incremental refactoring, and repeated prompt refinement. One caveat: the current release locates user messages through internal Chat DOM attributes rather than a stable third-party API. After a DSH upgrade, if the minimap stops working, disable the plugin and report your DSH version in GitHub Issues until upstream ships dedicated conversation-navigation hooks.
