+
+Custom queue and steering controls for DeepSeek Harness.
+
+## Features
+
+- `/queue [message]` appends a message to the current agent's next-turn queue.
+- `/steer [message]` sends a message to the active step (or follows up when idle).
+- **Queue & Steering** settings page controls the default busy-message mode, default list, and the batch template.
+- Replaces the built-in queue dock with two lists:
+  - **List 1 — all at once:** entries are presented as a batch.
+  - **List 2 — one at a time:** entries remain individual messages.
+- Queue rows can be reordered by dragging, moved between lists, edited inline, removed, or steered.
+- Escape exits editing and stores the in-progress value as a local draft; reopening the row restores it.
+
+## Development
+
+The plugin is loaded from the `link:` entry in the web profile. Host changes require a DSH restart; client changes require a browser refresh.
