-## Future Enhancements
+## 🚀 Future Enhancements
 
-1. ~~**Image Upload**: Implement Phoenix file uploads for component images~~ ✅ **COMPLETED**
-2. **Bulk Operations**: Import/export components via CSV
-3. **API Endpoints**: REST API for external integrations
-4. **User Management**: Multi-user support with roles and permissions
-5. **Advanced Search**: Filters by category, stock level, etc.
-6. **Barcode/QR Codes**: Generate and scan codes for quick inventory updates
+### Priority 1: Complete QR Code System (see [qr_storage_system](qr_storage_system.md))
+- **QR Code Image Generation** - Add Elixir library (e.g., `qr_code` hex package) to generate actual QR code images
+- **QR Code Display in Interface** - Show generated QR code images in the storage locations interface
+- **Camera Integration** - JavaScript-based QR scanning with camera access for mobile/desktop
+- **Multi-QR Code Detection** - Spatial analysis and disambiguation for multiple codes in same image
+
+### Component Management
+- **Barcode Support** - Generate and scan traditional barcodes in addition to QR codes
+- **Bulk Operations** - Import/export components from CSV, batch updates
+- **Search and Filtering** - Advanced search by specifications, tags, location
+- **Component Templates** - Reusable templates for common component types
+- **Version History** - Track changes to component specifications over time
+
+### Storage Organization  
+- **Physical Layout Mapping** - Visual representation of shelves, drawers, and boxes
+- **Bulk QR Code Printing** - Generate printable sheets of QR codes for labeling
 
 ## ✅ Recently Implemented Features
 
-### Image Upload System
+### Storage Location System Foundation 🚧 **PARTIALLY IMPLEMENTED**
+- **Database Schema** ✅ Complete - Hierarchical storage locations with parent-child relationships
+- **Storage Location CRUD** ✅ Complete - Full create, read, update, delete operations via web interface
+- **QR Code Data Generation** ✅ Complete - Text-based QR codes with format `SL:{level}:{code}:{parent}`
+- **Hierarchical Organization** ✅ Complete - Unlimited nesting (shelf → drawer → box)
+- **Web Interface** ✅ Complete - Storage locations management page with navigation
+- **Component-Storage Integration** ❌ Missing - Linking components to storage locations not yet implemented correctly
+
+### QR Code System - Still Needed 🚧 **NOT IMPLEMENTED**
+- **Visual QR Code Generation** ❌ Missing - No actual QR code images are generated
+- **QR Code Display** ❌ Missing - QR codes not shown in interface (as seen in screenshot)
+- **QR Code Scanning** ❌ Missing - No camera integration or scanning functionality
+- **QR Code Processing** ❌ Missing - Backend logic for processing scanned codes
+- **Multi-QR Disambiguation** ❌ Missing - No handling of multiple QR codes in same image
+
+### Image Upload System ✅ **COMPLETED**
 - **Phoenix LiveView file uploads** with `.live_file_input` component
 - **Image preview** during upload with progress indication
 - **File validation** (JPG, PNG, GIF up to 5MB)

+### Visual Datasheet Indicators ✅ **COMPLETED**
 - **Datasheet emoji** (📄) displayed next to component names when datasheet URL is present
 - **Clickable datasheet links** with clear visual indication
 - **Improved component listing** with image thumbnails and datasheet indicators
