Navigating lengthy or multi-turn conversations in DeepSeek Harness often becomes a frustrating exercise in manual screen scraping. Without a clear visual index, locating specific user prompts or confirming your exact scroll position requires relentless dragging. This friction not only disrupts cognitive flow but also triggers noticeable UI jank during traditional paginated history loads, making deep review unnecessarily tedious.

This plugin introduces a lightweight, always-present navigation rail that visually indexes every genuine user message along the right edge. A simple hover elegantly expands the rail into a single-line preview pane, enabling smooth click-to-jump highlighting while intelligently anchoring to your current reading position. Powered by a dedicated host-side session projection, the plugin instantly synchronizes the complete conversation history to the client side, eliminating initial loading delays. For environments where the projection registry isn't available, it gracefully degrades to a background on-demand pagination system.

Designed for power users who manage extended reasoning chains, developers debugging iterative prompt refinements, or researchers cross-referencing complex dialogue logs, this tool transforms chaotic scroll-heavy workflows into intuitive visual navigation. By injecting itself seamlessly into your profile stack, it delivers a clutter-free, performant way to traverse long chats without compromising the native streaming experience.
