dsh-turn-rail

When a multi-turn conversation in DeepSeek Harness Web grows long, scrolling back to an earlier exchange becomes tedious. You end up endlessly paging up or trying to remember where a particular turn landed. dsh-turn-rail adds a slim navigation rail along the right edge, bringing the see-every-turn-at-a-glance click-to-jump feel of the official DeepSeek chat page into Harness Web.

In its collapsed state the rail is just a 34-pixel strip; each user turn gets a small gray marker while the active turn turns blue and stretches slightly. As you scroll, scrollspy keeps the highlight in sync automatically. Hover over the rail or give it keyboard focus and it expands into a 240-pixel floating panel listing every user message one per row; clicking any row jumps straight to that turn. Opening a session triggers automatic pagination of older history, so all past turns show up in the rail without having to scroll to the very bottom.

It is built for developers who work through long, multi-turn sessions in Harness Web and frequently need to revisit or reference an earlier exchange. The plugin also ships an optional frosted-glass rounded background, off by default, that renders in both light and dark themes, giving the rail a floating-card look if you want that extra polish. Leave it off and you get a clean, minimal marker strip.
