## 🚀 How to Test

### Quick Start
1. Run `Supervertaler_v3.4.0-beta_CAT.py`
2. Go to **Resources > 🖼️ Load figure context...**
3. Select the `test_figures` folder
4. Click **Images tab** to see thumbnails
5. Import `test_figures/test_document.txt`
6. Translate segments with figure references
7. Check log for "[Figure Context] Detected references: ..."

### Detailed Testing
See `test_figures/TESTING_GUIDE.md` for complete testing instructions.

## 🎯 Next Steps

### Immediate (Recommended)
1. **Test the feature** using provided materials
2. **Verify multimodal API** integration works
3. **Report any issues** found during testing

### Short-term (Optional)
1. **Try with real documents** and actual figure images
2. **Test all three providers** (OpenAI, Claude, Gemini)
3. **Update USER_GUIDE.md** with figure context documentation

### Medium-term (Future)
1. **Continue modularization** with `api_client.py`
2. **Add more test cases** for edge scenarios
3. **Performance optimization** if needed

## 💡 Key Improvements

### For Users
- ✅ **Automatic figure detection** - No manual configuration
- ✅ **Visual feedback** - Thumbnails in Images tab
- ✅ **Transparent operation** - Switches to multimodal automatically
- ✅ **Project persistence** - Images reload with project

### For Developers
- ✅ **Clean architecture** - Figure context isolated in module
- ✅ **Testable code** - Module can be unit tested
- ✅ **Reusable components** - Module works standalone
- ✅ **Better maintainability** - Centralized logic

### For Codebase
- ✅ **Reduced duplication** - 3 duplicate functions eliminated
- ✅ **Better organization** - 200 lines moved to module
- ✅ **Consistent style** - British sentence case throughout

## 🐛 Known Issues

### Fixed
- ✅ Missing `ImageTk` import (fixed)
- ✅ Duplicate helper functions (consolidated)
- ✅ Mixed capitalization (standardized)

### Pending
- ⚠️ Project load still has some old code (not yet refactored to use manager)
- ⚠️ translate_current_segment has some old code (partially refactored)

Note: These are minor and don't affect functionality. Can be cleaned up in future refactoring.
