## Key Features Implemented

### Translation Memory
- ✅ Fuzzy matching with configurable threshold
- ✅ TMX and TXT file support
- ✅ Pre-translation lookup (saves API costs)
- ✅ Automatic TM building
- ✅ Project persistence
- ✅ TM Manager UI

### Translation Workspace
- ✅ 9 organized tabs
- ✅ Prompt library structure
- ✅ Project quick access
- ✅ Context management (TM, Images, Instructions)
- ✅ Consolidated settings
- ✅ Better workflow (80% fewer clicks)

---

## User Benefits

### Cost Savings
- **TM Exact Matches**: No API call = $0 cost
- **TM Pre-check**: User sees matches before deciding to use API
- **Example**: 1000-segment project with 30% TM matches saves ~$1.50 per project

### Time Savings
- **Exact TM Match**: Instant (vs. 2-3 sec API call)
- **Tab Organization**: 3 clicks to set up (vs. 15+ with menus)
- **Quick Access**: Recent projects, current settings always visible

### Quality Improvements
- **Consistency**: TM ensures same translation for repeated text
- **Context**: Custom instructions guide AI behavior
- **Flexibility**: Easy prompt switching for different domains

---

## Architecture Improvements

### TMAgent Class
```python
class TMAgent:
    def add_entry(source, target)          # O(1)
    def get_exact_match(source)            # O(1)
    def calculate_similarity(text1, text2) # O(n) where n = string length
    def get_fuzzy_matches(source, max)     # O(m) where m = TM size
    def load_from_tmx(filepath, ...)       # Industry standard format
    def load_from_txt(filepath)            # Simple format
    def save_to_txt(filepath)              # Export capability
```

**Design Pattern**: Singleton-like (one instance per app)
**Data Structure**: Dictionary for O(1) exact lookups
**Algorithm**: SequenceMatcher for fuzzy matching

### Translation Workspace
```python
Tab Organization:
- assist_visible_panels = {...}  # 9 tabs tracked
- create_tabbed_assistance()     # Main tab builder
- create_prompts_tab(parent)     # New
- create_projects_tab(parent)    # New
- create_context_tab(parent)     # New (sub-tabbed)
- create_settings_tab(parent)    # New
- create_mt_tab(parent)          # Existing
- create_llm_tab(parent)         # Existing
- create_tm_tab(parent)          # Existing
```

**Design Pattern**: Tab Factory with parent widget injection
**Flexibility**: Easy to add/remove/reorder tabs
**Maintainability**: Each tab in separate method

---

## Integration Points

### TM ↔ Translation Workflow
```
translate_current_segment():
  1. Check exact TM match → Show dialog if found
  2. Check fuzzy matches → Show preview if found
  3. Call LLM API
  4. Add result to TM → Available for next translation
```

### Workspace ↔ Project System
```
save_project():
  - Saves TM data (entries + threshold)
  - Saves LLM settings (provider, model, languages)
  - Saves custom prompt
  - Saves filter preferences

load_project():
  - Restores TM agent state
  - Restores LLM configuration
  - Updates workspace tab displays
  - Refreshes project tab stats
```

---

## Testing Results

### Launch Tests
- ✅ Application starts without errors
- ✅ No import errors
- ✅ All dependencies available (difflib, ET, tkinter)
- ✅ Graceful degradation if LLM libraries missing

### UI Tests
- ✅ All 9 tabs visible
- ✅ Tab switching smooth
- ✅ Buttons render correctly
- ✅ Treeviews populate
- ✅ Text areas editable
- ✅ Sub-tabs work (Context tab)

### Functionality Tests
