+
+## 🎯 RECOMMENDATIONS
+
+### Immediate Actions (High Priority)
+1. **Update Documentation** - Add "Status: Not Implemented" badges to docs for:
+   - `tocOptions`
+   - `bookmarkOptions`
+   - `templateOptions`
+   - `fontOptions`
+
+2. **Add Warnings** - In JSDoc comments for unimplemented features
+
+3. **README Update** - Clarify which advanced features are roadmap items
+
+### Quick Wins (COMPLETED!)
+1. ✅ **Metadata** - DONE
+2. ✅ **Basic Header/Footer** - DONE (text-based)
+3. ✅ **Media Type Emulation** - DONE (@media print CSS injection)
+4. ✅ **Header/Footer Templates** - DONE (full template system with variables)
+5. ✅ **PDF Security** - DONE (password protection & permissions)
+6. ✅ **PDF Preview** - DONE (real-time preview with live updates)
+
+### Future Roadmap (Complex)
+1. **Table of Contents** - Content analysis and page reference tracking
+2. **PDF Bookmarks** - Outline/navigation pane generation
+3. **Custom Fonts** - Font file loading and embedding
+4. **Template System** - Full template engine with loops and conditionals
+

+
+## 🔍 TESTING RECOMMENDATIONS
+
+### Core Features Test
+```typescript
+const options = {
+  orientation: 'portrait',
+  format: 'a4',
+  margins: [20, 20, 20, 20],
+  showPageNumbers: true,
+  customCSS: 'body { font-family: Arial; }',
+  watermark: {
+    text: 'CONFIDENTIAL',
+    opacity: 0.1,
+    position: 'diagonal'
+  },
+  metadata: {
+    title: 'Test Document',
+    author: 'Test User',
+    subject: 'Feature Test'
+  },
+  securityOptions: {
+    enabled: true,
+    userPassword: 'secret123',
+    permissions: {
+      printing: 'highResolution',
+      copying: false,
+      modifying: false
+    }
+  }
+};
+```
+
+### Features to Avoid (Until Implemented)
+```typescript
+// DON'T USE - Not implemented:
+const badOptions = {
+  tocOptions: { /* ... */ },      // ❌ Not working
+  bookmarkOptions: { /* ... */ }, // ❌ Not working
+  templateOptions: { /* ... */ }, // ❌ Not working
+  fontOptions: { /* ... */ },     // ❌ Not working
+  asyncOptions: { /* ... */ },    // ❌ Not working
+};
+```
+
