dsh-conversation-nav

Once a conversation in the DeepSeek Harness Web GUI stretches past a few dozen turns, scrolling back to a specific message becomes a tedious, memory-dependent exercise. dsh-conversation-nav brings the signature piano-key rail from the Codex desktop client into the browser: a vertical column of ticks along the left edge of the chat area, one per user message, turning any long thread into an instantly navigable timeline.

Hover over a tick to reveal a detail card with a one-line message summary, up to three lines of the model reply preview, and a meta line showing send time (HH:mm for today, M-dd HH:mm this year, full date across years), round duration, and output token count. Click to smooth-scroll to that turn with a brief highlight; while scrolling, the tick for the turn you are reading darkens in real time so you always know your position. Right-click a tick to cycle through amber, red, blue, and green markers, optionally attach a text note, and all marks persist per session in localStorage across reloads. The plugin is fully event-driven with no persistent timers, so even very long conversations stay fluid.

If you routinely work through dozens or hundreds of turns with DeepSeek in the web interface and need to revisit, compare, or annotate key exchanges, this zero-dependency, purely client-side plugin gives you that navigation out of the box.
