  This extension gives you a clear and simple way to monitor the remaining battery percentage on your laptop, with powerful features to keep you informed, including visual notifications and audio alarms.
  
  Core Features:
  
  Powerful Alarms: Click the percentage inside the floating window to access the settings panel. Here, you can configure detailed alarms to notify you at specific battery levels, whether your device is charging or discharging.
  
  Customizable Notifications: Choose from several built-in sounds for your alarms to ensure you never miss an important battery event. The extension comes with smart defaults to get you started: an alarm at 88% while charging and at 22% while discharging.
  
  Live Toolbar Icon: The extension icon dynamically draws your current battery percentage, updating every minute. The icon's colors automatically adapt to your browser's light or dark theme.
  
  Floating Window: Click the toolbar icon to open a compact, standalone window with the battery percentage in a large, easy-to-read font. Because it's a true window, it stays open so you can keep an eye on your battery while you work. Clicking the icon also instantly refreshes the battery level.
  
  Full Dark Mode: A dedicated dark mode is available for both the main display and the settings window for comfortable viewing in any lighting. Your preference is saved and applied instantly across both windows.
