dsh-qnav

Long DSH conversations can easily stretch into hundreds of turns, and finding a specific question you asked earlier means endless upward scrolling. dsh-qnav adds a slim question-navigation rail along the right edge of the chat: every real user question becomes a hoverable tick you can click to jump straight to that turn, with the current scroll position highlighted automatically. What used to be a blind sweep is now a single click.

The rail identifies genuine user questions via the data-chat-flow-kind="user" attribute, automatically excluding uncommitted inputs, system-injected context rows, and steering messages so you never see misleading empty ticks. Jumping works by storing a direct DOM element reference and calling scrollIntoView(), which sidesteps the dedup bugs, prefix collisions, and @-reference text-node splits that plague text-prefix matching. The current-position highlight is computed from element bounding rectangles rather than fragile text-tree walks, making it immune to quoted content inside assistant answers. Tick spacing adapts proportionally as questions accumulate, dark-mode highlight colors follow the system theme automatically, and hover tooltips show a sequence number on the left while staying within the viewport.

A MutationObserver with a 500 ms debounce keeps the rail in sync as content changes, and the disposer returned from apply(ctx) tears down observers, intervals, injected DOM nodes, and stylesheets cleanly on hot-reload or disable. Being a pure client-side plugin with no sandbox changes required, it works in any DSH Web environment and is well suited for developers who regularly handle long contexts and need to revisit past questions frequently.
