## Power Features
- **Smart Process Names**: Shows user-friendly names (e.g., "Google Chrome" instead of "chrome")
- **Fast Process Icons**: Optimized text-based icons ([Web], [Dev], [DB], [Sys], etc.)
- **Multiple Sort Modes**: Sort by CPU usage (default), memory usage, name, or PID (works in both flat and tree view)
- **Enhanced Process Tree**: Proper tree structure with ├── and └── symbols, sorted at each level
- **Visual Resource Usage**: CPU and memory bars with color-coded indicators (░▒▓█)
- **High Usage Alerts**: 🔥 for high CPU, 💾 for high memory usage
- **Parent Process Info**: Shows parent PID for process relationships
- **Smart Filtering**: Filter/search works correctly without interfering with hotkeys
- **High Performance**: Optimized for fast loading and responsive UI
- **Flexible Startup**: Start with either ports or processes view using command line flags
- **Permission Management**: Intelligent permission checking with sudo suggestions

### Fallback Mechanisms
The application includes comprehensive fallback mechanisms:
- If `lsof` is not available, falls back to `netstat`
- If extended `ps` options fail, uses basic `ps` commands
- Multiple kill methods for different permission levels
- Graceful degradation when commands are not available

### Permission Management
- **Automatic Detection**: Shows current user and privilege level
- **Smart Error Messages**: Identifies permission-related failures
- **Sudo Suggestions**: Recommends using sudo when needed
- **Safe Testing**: Pre-checks permissions before attempting to kill processes

### Running with Elevated Privileges
```bash
# For killing system processes
sudo pttr
```
