dsh-session-nav

Long conversations make it tedious to scroll back to a specific prompt, check how long a turn took, or review which files were edited. dsh-session-nav overlays a vertical rail on the left side of the conversation column, compressing every user message, steering command, or slash-command turn into a single short dash so you can see the full structure of a session at a glance without leaving the current view.

Hovering over the rail triggers a staggered wave that lengthens neighbouring dashes and reveals a prompt bubble, a Worked for duration, and an Edited N files +X −Y card summarising file edits. Clicking any dash or pressing the up/down arrow keys scrolls that turn into view. Turns that Chat has not yet loaded are paged from session.history on demand, so you can navigate even very early conversation history. The rail caps at 66 percent of the column height, scrolls internally when the stack is long, and a toggle in the session header persists your preference in localStorage.

Ideal for DeepSeek Harness power users who iterate across many turns and need to quickly revisit past prompts, compare per-turn durations, or audit file-level changes. It is a pure overlay that does not replace Chat, the sidebar, or the Trajectory tab, and it coexists with other layout plugins.
