dsh-trail-plugin

DSH conversations are a linear, append-only log. You can scroll down, but finding back to exactly what was said three turns ago is painful, and forking a new path from an earlier node is simply impossible out of the box. dsh-trail-plugin adds a History Index panel on the left side of the session list, collapsing each conversation event log into an expandable node tree so the linear record finally has an indexable, jumpable, forkable navigation layer.

The workflow is straightforward: click any node and the chat stream scrolls to that turn, auto-loading older content if needed; hover a node and hit Fork to spawn a child session from that point without disturbing the current one; nodes with branches show a numeric badge, click to expand a dropdown and switch branches instantly. Panel width and collapsed state persist across refreshes, and the index is stored via DSH official projection channel, surviving restarts regardless of how many messages the window has loaded.

It is built for developers who frequently need to revisit long conversations, explore multiple branches of the same prompt, or repeatedly fork from mid-session nodes in agent pipelines. The plugin is read-only on event logs, never mutates session data, and uses the official sessions.fork API. Install it, restart DSH, and the panel appears on the left.
