## 🎓 How It Works

### 1. User Interaction
```
User hovers → Plus button appears → Menu opens → "New Document" clicked
```

### 2. Component Creation
```typescript
// In MainPanelLayout.tsx
const docId = `doc-${Date.now()}`;
newContainer.content = (
  <DocEditor
    docId={docId}
    initialContent=""
    onSave={(content) => {
      console.log('Document saved:', docId, content);
    }}
  />
);
```

### 3. Editor Initialization
```typescript
// In DocEditor.tsx
const editor = useEditor({
  extensions: [
    StarterKit,
    Placeholder,
    Underline,
    TextAlign,
    Link,
    Image,
    // ... more extensions
  ],
  content: initialContent,
  editable: !readOnly,
});
```

### 4. Auto-Save
```typescript
useEffect(() => {
  const saveInterval = setInterval(() => {
    const content = editor.getHTML();
    onSave(content);
  }, 30000); // 30 seconds
  
  return () => clearInterval(saveInterval);
}, [editor, onSave]);
```
