- Grayscale mode toggle
- Palette mode toggle
- 💾 **Save Function**: Save processed images to gallery
- 🖼️ **Focused Display**: Shows only the processed pixel art effect with a cleaner interface
- 🔧 **Smart Processing**: Supports large images (2000x2000+) with automatic memory management

## Technical Implementation

### Core Algorithm
Based on the original JavaScript version algorithm, reimplemented and optimized in Kotlin:

1. **Pixelation Processing**:
- Smart large image handling (auto-adjusts scale for >900px images)
- Precise boundary calculations to avoid cropping issues
- Optimized drawing methods using Rect for precise control

2. **Color Similarity Calculation**: Uses Euclidean distance for color similarity calculation

3. **Palette Mapping**:
- Batch pixel processing for 6-7x performance improvement
- Proper transparency handling
- Optimized memory management

4. **Grayscale Conversion**: RGB average value calculation for grayscale (consistent with original algorithm)
