So many thanks for implementing the window state persistence feature!

The implementation looks thoughtful and handles the multi-monitor scenario well. Here are some thoughts that might be helpful:

1. We might want to consider adding maximized state handling?

// Example approach:
electronStore.set('windowState', {
  bounds: win.getBounds(),
  isMaximized: win.isMaximized()
})

2. Would it make sense to add some error handling? Something like:

try {
  win.setBounds(savedBounds)
} catch (error) {
  // log some error here
  console.error('Failed to restore window bounds:', error)
  // Handle fallback
}

3. Can we sync the latest window size values to the database for better persistence?

Only when we open it for the first time do we use 1025 * 749 as the default value?

const defaultBounds = {
  width: 1024,
  height: 768,
  x: 0,
  y: 0
}
