## Usage

### Basic Component Usage

```python
from twitter_streamlit_ui.components.cards import FeatureCard
from twitter_streamlit_ui.components.forms import TweetForm
from twitter_streamlit_ui.styles.theme import apply_theme

# Apply theme
apply_theme()

# Use components
feature_card = FeatureCard(
    title="Tweet Generator",
    description="Create engaging tweets with AI",
    icon="🐦"
)
feature_card.render()

tweet_form = TweetForm()
tweet_form.render()
```

### State Management

```python
from twitter_streamlit_ui.utils.state import StateManager

# Initialize state
state = StateManager()
state.initialize()

# Update state
state.update("current_tweet", tweet_data)
```

### Error Handling

```python
from twitter_streamlit_ui.components.feedback import ErrorBoundary

with ErrorBoundary():
    # Your code here
    pass
```

## Best Practices

1. **Component Reusability**
   - Use existing components when possible
   - Create new components only when necessary
   - Follow the established patterns

2. **State Management**
   - Use the StateManager for all state
   - Avoid direct session state manipulation
   - Keep state updates atomic

3. **Performance**
   - Use lazy loading for heavy components
   - Implement caching where appropriate
   - Monitor render performance

4. **Accessibility**
   - Include ARIA labels
   - Ensure keyboard navigation
   - Test with screen readers

5. **Error Handling**
   - Use ErrorBoundary components
   - Provide clear error messages
   - Include recovery options

## Future Improvements

1. **Component Library**
   - Add more specialized components
   - Enhance existing components
   - Create component documentation

2. **Theme System**
   - Add more theme options
   - Implement theme switching
   - Create custom theme builder

3. **Performance**
   - Implement virtual scrolling
   - Add performance monitoring
   - Optimize resource loading

4. **Testing**
   - Add component tests
   - Implement E2E tests
   - Create test documentation
