    this.setupServiceWorker();
    this.initOfflineStorage();
  }

  setupServiceWorker() {
    if ('serviceWorker' in navigator) {
      navigator.serviceWorker.register('/sw.js')
        .then(registration => {
          console.log('Offline functionality enabled');
        });
    }
  }

  initOfflineStorage() {
    // Use IndexedDB to store offline data
    this.db = new IndexedDB('notebook-offline');
    this.syncQueue = new OfflineSyncQueue();
  }

  saveOffline(content) {
    // Save content offline
    this.db.save(content);
    this.syncQueue.add(content);
  }

  syncWhenOnline() {
    // Auto sync when network recovers
    window.addEventListener('online', () => {
      this.syncQueue.process();
    });
  }
}
