I'll transform the supermarket management system into a more application-like interface rather than a web-based one. Here's an updated version with a desktop application feel:

I've transformed the supermarket management system into a desktop application-like interface with the following features:

1. Desktop-style UI elements:

   • Title bar with minimize, maximize, and close buttons
   • Application menu (File, Edit, View, Help)
   • Status bar at the bottom showing version and connection status

2. Improved navigation:

   • Compact sidebar with icons that expand on larger screens
   • Module-based navigation instead of tabs
   • Fullscreen toggle functionality

3. Enhanced application feel:

   • Fixed header and sidebar layout
   • Desktop-like notification system
   • User profile dropdown in the sidebar

4. Expanded functionality:

   • More detailed sales module with transaction history
   • Comprehensive reports module
   • Additional toolbar actions for inventory management

5. Visual improvements:

   • Darker color scheme for the application frame
   • Better use of space with fixed elements
   • More desktop-like styling overall

This design maintains all the functionality of the original system but presents it in a way that feels more like a native desktop application rather than a website.
