+## CueProgBar - Progress Bar Window
+
+CueProgBar is a lightweight, standalone progress monitoring window that provides a visual representation of job frame status. It offers a minimalist interface for quick job monitoring without the overhead of the full CueGUI application.
+
+### Launching CueProgBar
+
+From CueGUI Job Context Menu:
+   - Right-click on any job in the Monitor Jobs view
+   - Select "Show Progress Bar" from the context menu
+   - A separate progress bar window opens for that job
+
+### Interface Overview
+
+![CueProgBar Window Interface](/assets/images/cuegui/cueprogbar/cueprogbar_window.png)
+
+The CueProgBar window consists of three main components:
+
+1. **Visual Progress Bar**: A horizontal bar showing frame states through color coding
+2. **Status Label**: Displays current progress (e.g., "150 of 200 done, 10 running")
+3. **Job Name Label**: Shows the full job name
+
+### Frame State Color Coding
+
+The progress bar uses distinct colors to represent different frame states:
+
+| State | Color | Description |
+|-------|-------|-------------|
+| **SUCCEEDED** | Green (#37C837) | Frames that completed successfully |
+| **RUNNING** | Yellow (#C8C837) | Frames currently being processed |
+| **WAITING** | Light Blue (#87CFEB) | Frames ready to run when resources are available |
+| **DEPEND** | Purple (#A020F0) | Frames waiting on dependencies |
+| **DEAD** | Red (#FF0000) | Frames that failed and exceeded retry attempts |
+| **EATEN** | Dark Red (#960000) | Frames manually marked as complete |
+

+
+### Interactive Features
+
+#### Left-Click Menu
+
+Clicking the left mouse button on the progress bar displays a breakdown of frame states:
+
+![CueProgBar Frame Status Menu](/assets/images/cuegui/cueprogbar/cueprogbar_left_click.png)
+
+- Shows count for each frame state
+- Color-coded icons match the progress bar colors
+- Only displays states with non-zero counts
+
+#### Right-Click Context Menu
+
+Right-clicking the progress bar reveals job control actions:
+
+![CueProgBar Context Menu](/assets/images/cuegui/cueprogbar/cueprogbar_right_click.png)
+
+Available actions include:
+
+1. **Pause/Unpause Job**:
+   - Toggles job execution state
+   - Paused jobs show "Paused" overlay on the progress bar
+   - Prevents new frames from starting while allowing running frames to complete
+
+2. **Retry Dead Frames** (NEW):
+   - Appears only when dead frames exist
+   - Shows confirmation dialog with dead frame count
+   - Retries all frames in DEAD state
+   - Displays success/failure notification
+
+   ![Retry Dead Frames Confirmation](/assets/images/cuegui/cueprogbar/cueprogbar_retry_confirm.png)
+
+3. **Kill Job**:
+   - Terminates the job and all running frames
+   - Requires confirmation dialog
+   - Logs the action with username and timestamp
+
+### Window Features
+
+#### Auto-Update
+- Refreshes every 5 seconds (configurable)
+- Updates frame counts and progress bar in real-time
+- Stops updating when job completes
+
+#### Window Title
+The window title dynamically updates to show:
+- **Percentage**: "75% job_name" (for running jobs)
+- **DONE**: "DONE job_name" (for completed jobs)
+- **ERR**: "ERR job_name" (when dead frames exist and no frames are running)
+
+#### Visual Indicators
+- **COMPLETE** overlay: Displayed when job finishes successfully
+- **Paused** overlay: Shown when job is paused
+- **Job Not Found** message: Appears if job is deleted or becomes inaccessible
+
+### Use Cases
+
+CueProgBar is ideal for:
+
+1. **Quick Monitoring**: Artists who want to monitor specific jobs without full CueGUI
+2. **Multi-Job Tracking**: Opening multiple progress bars for different jobs simultaneously
+3. **Desktop Integration**: Minimal windows that can be arranged on secondary monitors
+4. **Resource Efficiency**: Lower memory and CPU usage compared to full CueGUI
+
+### Technical Details
+
+#### Memory Usage
+- Minimal memory footprint
+- No layer or frame detail caching
+- Simple RPC calls for job statistics only
+
+#### Update Mechanism
+```python
+# Update cycle (every 5 seconds)
+1. Fetch job statistics via RPC
+2. Calculate frame state totals
+3. Repaint progress bar
+4. Update labels and title
+```
+
+### Best Practices
+
+1. **Multiple Windows**: Open separate progress bars for critical jobs
+2. **Window Arrangement**: Stack vertically for space-efficient monitoring
+3. **Close When Done**: Windows can be safely closed without affecting jobs
+4. **Retry Strategy**: Use "Retry Dead Frames" before marking jobs complete
