Turn histogram navigation rail for DeepSeek Harness Web with mixed, DeepSeek, and Codex visual variants.

Unfocused turns render as short bars on the right edge of the conversation. Hovering or keyboard-focusing a bar grows it into a wave (the focused bar is longest) and shows a preview card with the message you sent in that turn. While sweeping along the rail, the preview card stays visible and smoothly slides to the active bar, showing that turn's message text. Clicking a bar smooth-scrolls the conversation to that turn.

Install

dsh plugin --profile web add git+https://github.com/xiaheng1/dsh-turn-nav.git
dsh plugin --profile web install

Then restart dsh web and hard-refresh the browser (Ctrl+F5).

For a local folder:

dsh plugin --profile web add <absolute-path-to-this-folder>
dsh plugin --profile web install

Usage

1. Open a workspace and a conversation.
2. Move the pointer over the right-edge rail: the bar under the pointer grows, adjacent bars form a wave, and a shared preview card smoothly slides to the active bar showing that turn's message.
3. Click a bar to smooth-scroll to that turn.

The rail hides on narrow screens (max-width: 767px) by default; set hideOnNarrow: false to keep it visible.

Configuration

The quickest way to change defaults is to edit dsh-turn-nav.config.json in the repository/package root. The plugin reads it at startup as the base layer; if the file is missing, built-in defaults are used.

For per-deployment overrides, the plugin also registers a dsh-turn-nav settings namespace. Edit $DSH_HOME/settings.yaml (or settings.json) to override defaults:

dsh-turn-nav:
  waveTransitionMs: 120
  barWidth: 14
  focusedBarWidth: 30
  previewEnabled: true

You can also read and update the effective config from the browser console:

// Read the currently effective config.
dshTurnNav.getConfig()

// Update one or more fields (persisted through DSH settings).
dshTurnNav.updateConfig({ waveTransitionMs: 120 })

// Clear all user overrides and return to defaults.
dshTurnNav.resetConfig()

If a field is not configured, the default is used. The defaults keep the original short-bar feel while making the focused wave softer and rounder.

Variants

Set variant to choose the visual style:

Package layout

• lib/client.js — prebuilt browser plugin bundle (committed for direct use).
• lib/index.js — node half; registers the dsh-turn-nav settings namespace and reads the root config file.
• dsh-turn-nav.config.json — root-level defaults you can edit directly.
• src/ — source code for reference.
