dsh-jumpbar

When you are deep into a multi-turn conversation in the DeepSeek Harness web GUI, jumping back to one of your own earlier prompts usually means dragging the scrollbar back and forth. dsh-jumpbar floats a minimap-style dash strip along the right edge of the chat column, with each dash mapped to the exact vertical position of one user message in the full transcript, giving you an instant spatial overview of where every prompt sits.

The strip goes beyond a simple locator. Hovering a dash reveals a text preview beside the strip and faintly highlights the matching row in the transcript without touching product DOM. Clicking smooth-scrolls the target message to the top with a brief brand-color flash. Pressing the space between dashes and dragging lets you scrub through the entire transcript with pointer capture keeping the gesture alive. New messages, loaded history, window resizes, and session switches all trigger a live re-computation via MutationObserver and ResizeObserver with rAF throttling, so the dashes always stay in sync with the current layout.

Built for developers who regularly work through long, multi-turn conversations in the DSH web GUI and need to revisit their own prompts and surrounding context often. The plugin runs entirely in the browser, registers a single shell.overlay entry, changes no product code, stays fully hidden when no user message exists, and has zero layout impact.
