dsh-sctrk

When a single DSH session has grown to hundreds of messages—user questions, multi-step reasoning, tool calls, command executions, compaction records all tangled together—scrolling to find a specific node is slow and tedious. dsh-sctrk renders an 8px-wide floating session scroll-track along the interface edge, compressing the entire conversation into a visual map you can navigate by sight instead of by scrollbar. Each tick is color-coded by node type (a muted Morandi palette distinguishes user, assistant, tool, command, compaction, error, and more), while dense regions automatically merge into gradient clusters; clusters containing user messages carry a steel-blue anchor for quick identification. Hovering near the track magnet-snaps the nearest tick to elongate and darken, and summons a frosted-glass preview card showing the cluster composition plus up to 12 evenly-sampled content snippets. Clicking a tick, cluster, or preview entry jumps precisely to that node, while dragging the track scrolls proportionally. The plugin is fully self-contained with no build step and zero dependencies beyond React, adapting to DSH light and dark themes automatically. ResizeObserver and MutationObserver keep the track in sync as the window resizes or new messages arrive, so the map updates the moment a new tool call lands. It is best suited for engineers and researchers who run long, multi-turn reasoning sessions with heavy tool-calling in DSH and frequently need to backtrack, compare, or revisit specific historical nodes.
