+
+## UI Components
+
+### Styled Card Widget
+
+```python
+from PyQt6.QtWidgets import QFrame, QVBoxLayout, QLabel
+
+def create_card(self, title, content):
+    """Create a styled card widget."""
+    card = QFrame()
+    card.setStyleSheet("""

+
+### Progress Widget
+
+```python
+from PyQt6.QtWidgets import QProgressBar, QLabel, QVBoxLayout, QWidget
+
+def create_progress_widget(self):
+    """Create a progress display widget."""
+    widget = QWidget()

+            table.setItem(row, col, QTableWidgetItem(str(value)))
+```
+

+
+## Advanced Patterns
+
+### Singleton Pattern
+
+```python
+class MyService:
+    """Singleton service example."""
+    
+    _instance = None
+    
+    def __new__(cls):
+        if cls._instance is None:
+            cls._instance = super().__new__(cls)
+            cls._instance._initialized = False
+        return cls._instance
+    
+    def __init__(self):
+        if self._initialized:
+            return
+        self._initialized = True
+        # Initialize here
+```
+
+### Plugin Communication
+
+```python
+def register_api_endpoint(self):
+    """Register an API for other plugins."""
+    from core.plugin_api import APIEndpoint, APIType
+    
+    endpoint = APIEndpoint(
+        name="get_my_data",
+        api_type=APIType.CUSTOM,
+        description="Get data from this plugin",
+        handler=self.provide_data,
+        plugin_id=self._plugin_id,
+        version="1.0.0"
+    )
+    
+    self.register_api(endpoint)
+
+def use_other_plugin_api(self):
+    """Call API from another plugin."""
+    result = self.call_api("other_plugin", "their_api", arg1, arg2)
+    return result
+```
+
+### Error Handling Pattern
+
+```python
+def safe_operation(self):
+    """Operation with proper error handling."""
+    try:
+        result = self.risky_operation()
+        return result
+    except NetworkError as e:
+        self.log_warning(f"Network error: {e}")
+        self.notify_warning("Connection Issue", "Please check your internet connection.")
+    except ValueError as e:
+        self.log_error(f"Invalid value: {e}")
+        self.notify_error("Error", f"Invalid input: {e}")
+    except Exception as e:
+        self.log_exception(f"Unexpected error: {e}")
+        self.notify_error("Error", "An unexpected error occurred.")
+    
+    return None
+```
+
+### Context Manager for Resources
+
+```python
+from contextlib import contextmanager
+
+@contextmanager
+def temp_file(self, suffix='.tmp'):
+    """Context manager for temporary files."""
+    import tempfile
+    
+    fd, path = tempfile.mkstemp(suffix=suffix)
+    try:
+        os.close(fd)
+        yield path
+    finally:
+        if os.path.exists(path):
+            os.remove(path)
+
+def process_with_temp(self, data):
+    """Use temporary file safely."""
+    with self.temp_file() as temp_path:
+        with open(temp_path, 'w') as f:
+            f.write(data)
+        # Process temp file
+        result = self.process_file(temp_path)
+    # File automatically cleaned up
+    return result
+```

+### Q: Can I disable plugins I don't use?
+**A:** Yes! Go to Settings → Plugins and uncheck the plugins you don't want to load. This improves startup time and reduces memory usage.
+
+### Q: How do I create my own plugin?
+**A:** See the [Plugin Development Guide](docs/PLUGIN_DEVELOPMENT_GUIDE.md). The basic structure is:
+```python
+from plugins.base_plugin import BasePlugin
+
+class MyPlugin(BasePlugin):
+    name = "My Plugin"
+    version = "1.0.0"
+    def initialize(self): pass
+    def get_ui(self): return my_widget
+```
+
+### Q: Does the loot tracker work automatically?
+**A:** Yes, the loot tracker reads from your chat.log file automatically. Make sure:
+1. EU-Utility knows your Entropia Universe installation path
+2. The loot tracker plugin is enabled
+3. You're using the in-game loot window
+
+### Q: How does the Discord Rich Presence work?
+**A:**
+1. Install `pypresence`: `pip install pypresence`
+2. Create a Discord application at discord.com/developers
+3. Copy the Client ID to the Discord Presence plugin
+4. Enable the plugin
+
+---
+
+## Troubleshooting
+
+### Q: EU-Utility won't start, what should I do?
+**A:** Try these steps:
+1. Check Python version: `python --version` (need 3.11+)
+2. Reinstall dependencies: `pip install --force-reinstall -r requirements.txt`
+3. Clear settings: Delete `~/.eu-utility/settings.json`
+4. Check logs: Look in `~/.eu-utility/logs/`
+
+### Q: Hotkeys aren't working
+**A:**
+1. Run EU-Utility as Administrator
+2. Check if another app is using the same hotkeys
+3. Change hotkeys in Settings → Hotkeys
+4. Restart EU-Utility after changing hotkeys
+
+### Q: The overlay disappears when I click the game
+**A:**
+1. Right-click the floating icon
+2. Disable "Click-through" mode
+3. Or pin the overlay using the pin button
+
+### Q: OCR isn't working
+**A:**
+1. Install EasyOCR: `pip install easyocr`
+2. Ensure game window is visible (not minimized)
+3. Try increasing game brightness
+4. First run downloads models (may take a few minutes)
+
+### Q: I get "ModuleNotFoundError" errors
+**A:** Install missing dependencies:
+```bash
+pip install -r requirements.txt
+```
+
+### Q: The floating icon is missing
+**A:**
+1. Check system tray (may be minimized there)

+# Convert to EU-Utility format
+sessions = []
+current_session = {
+    'start_time': df.iloc[0]['date'] + ' ' + df.iloc[0]['time'],
+    'items': [],
+    'total_tt': 0
+}
+
+for _, row in df.iterrows():
+    item = {
+        'name': row['item_name'],
+        'value': float(row['tt_value']),
+        'quantity': int(row.get('quantity', 1))
+    }
+    current_session['items'].append(item)
+    current_session['total_tt'] += item['value']
+
+sessions.append(current_session)
+
+# Save
+data = {'loot_tracker': {'sessions': sessions}}
+with open('import_ready.json', 'w') as f:
+    json.dump(data, f, indent=2)
+```

+
+## Troubleshooting Migration
+
+### Issue: Import Fails
+**Solution:**
+1. Check file format is valid JSON
+2. Verify required fields are present
+3. Check file encoding (should be UTF-8)
+4. Try smaller chunks if file is large
+
+### Issue: Data Looks Wrong
+**Solution:**
+1. Check date/time formats
+2. Verify PED values are numbers, not strings
+3. Check for missing required fields
+4. Validate JSON structure
+
+### Issue: Settings Don't Transfer
