## 🛡️ Safety Features

### Failsafe Mode

Move mouse to **any corner** of the screen to abort all automation.

```python
# Enable failsafe (enabled by default)
dc = DesktopController(failsafe=True)
```

### Pause Control

```python
# Pause all automation for 2 seconds
dc.pause(2.0)

# Check if automation is safe to proceed
if dc.is_safe():
    dc.click(500, 500)
```

### Approval Mode

Require user confirmation before actions:

```python
dc = DesktopController(require_approval=True)

# This will ask for confirmation
dc.click(500, 500)  # Prompt: "Allow click at (500, 500)? [y/n]"
```

---

## 🎨 Advanced Examples

### Example 1: Automated Form Filling

```python
dc = DesktopController()

# Click name field
dc.click(300, 200)
dc.type_text("John Doe", wpm=80)

# Tab to next field
dc.press('tab')
dc.type_text("john@example.com", wpm=80)

# Tab to password
dc.press('tab')
dc.type_text("SecurePassword123", wpm=60)

# Submit form
dc.press('enter')
```

### Example 2: Screenshot Region and Save

```python
# Capture specific area
region = (100, 100, 800, 600)  # left, top, width, height
img = dc.screenshot(region=region)

# Save with timestamp
import datetime
timestamp = datetime.datetime.now().strftime("%Y%m%d_%H%M%S")
img.save(f"capture_{timestamp}.png")
```

### Example 3: Multi-File Selection

```python
# Hold Ctrl and click multiple files
dc.key_down('ctrl')
dc.click(100, 200)  # First file
dc.click(100, 250)  # Second file
dc.click(100, 300)  # Third file
dc.key_up('ctrl')

# Copy selected files
dc.hotkey('ctrl', 'c')
```

### Example 4: Window Automation

```python
# Activate Calculator
dc.activate_window("Calculator")
time.sleep(0.5)

# Type calculation
dc.type_text("5+3=", interval=0.2)
time.sleep(0.5)

# Take screenshot of result
dc.screenshot(filename="calculation_result.png")
```

### Example 5: Drag & Drop File

```python
# Drag file from source to destination
dc.drag(
    start_x=200, start_y=300,  # File location
    end_x=800, end_y=500,       # Folder location
    duration=1.0                 # Smooth 1-second drag
)
```

## ⚡ Performance Tips

1. **Use instant movements** for speed: `duration=0`
2. **Batch operations** instead of individual calls
3. **Cache screen positions** instead of recalculating
4. **Disable failsafe** for maximum performance (use with caution)
5. **Use hotkeys** instead of menu navigation

---

## ⚠️ Important Notes

- **Screen coordinates** start at (0, 0) in top-left corner
- **Multi-monitor setups** may have negative coordinates for secondary displays
- **Windows DPI scaling** may affect coordinate accuracy
- **Failsafe corners** are: (0,0), (width-1, 0), (0, height-1), (width-1, height-1)
- **Some applications** may block simulated input (games, secure apps)

---

## 🔧 Troubleshooting

### Mouse not moving to correct position
- Check DPI scaling settings
- Verify screen resolution matches expectations
- Use `get_screen_size()` to confirm dimensions

### Keyboard input not working
- Ensure target application has focus
- Some apps require admin privileges
- Try increasing `interval` for reliability

### Failsafe triggering accidentally
- Increase screen border tolerance
- Move mouse away from corners during normal use
- Disable if needed: `DesktopController(failsafe=False)`

### Permission errors
- Run Python with administrator privileges for some operations
- Some secure applications block automation
