dsh-message-map

Losing track of a specific message in a long DSH conversation forces you to scroll endlessly through the chat log. dsh-message-map ports the Codex-style message navigation rail into DSH, drawing a vertical tick track along the left edge of the chat area so you can jump to any user message without scrolling.\n\nThe rail is driven entirely by already-rendered session nodes. It never mutates message data or executes Host commands, making it a pure read-only visual aid. Once a conversation accumulates four user messages, the ticks appear automatically with no toggle needed. Hovering reveals a message summary and context-injection source; clicking eases to the target with a 200 ms animation and a brief highlight; dragging lets you scan the whole axis at a glance. Appends, history loads, window resizes, and scroll changes are all tracked, keeping the rail in sync with live state.\n\nBuilt for developers who run long multi-turn sessions, chain tool calls, or repeatedly debug context in DSH. Instead of hunting through dozens of messages from memory, you can jump straight back to the original prompt or a mid-conversation tool return and focus on reasoning rather than scrolling.
