- Add toggle between Smart Scan (jscanify) and Manual Crop (cropper.js) modes - Default to Manual Crop mode on touch devices for easier mobile use - Integrate cropper.js with pinch-to-zoom, pan, and touch-friendly handles - Increase corner point size and button sizes for better touch targets - Add mobile help text and visual guidance - Maintain backward compatibility with existing scanner functionality - Improve touch event handling to prevent unwanted scrolling
