dsh-plugin-message-timeline-navigation

When a DSH conversation stretches past a hundred messages, scrolling back to the third turn to re-read a prompt becomes a chore. dsh-plugin-message-timeline-navigation drops a Codex-style vertical rail of dense short ticks along the left edge of the chat view, where each tick maps to one complete user turn—your message plus the full assistant reply—giving you an at-a-glance sense of how many exchanges the session contains.

Hover a tick and it elongates while its three nearest neighbors on each side expand in a stepped cascade, revealing a small preview card of the message text. Click it and the view smoothly scrolls to that turn, top-aligned with a brief highlight. Scroll naturally and the tick for the currently visible turn stays dark on its own, so the rail doubles as a passive reading-progress indicator. The whole thing is a pure front-end overlay: it mounts its own React root, reads DSH's public DOM contract, and leaves the DSH binary untouched.

If your day-to-day involves multi-turn debugging sessions, long code-generation chains, or extended research conversations in the DSH web client, this plugin turns that endless text stream into a navigable timeline. No sidebar toggle, no search bar—just glance at the rail, click, and land.
