A minimal macOS application that displays a simple counter in a popover anchored to the display notch.

• Counter Display: Shows an integer counter.
• Increment/Decrement: Buttons to increase or decrease the counter value.
• Notch Integration:
  • The popover appears attached to the screen notch.
  • Clicking near the notch area (or a defined trigger) opens/closes the popover.
  • The popover automatically closes when the application loses focus.
• Launch at Login: Can be configured to launch automatically when the user logs in.

This application is a significantly stripped-down version of the original NotchDrop application, focusing solely on demonstrating a basic notch-integrated UI with a counter. It's built using SwiftUI for the UI elements and AppKit for window management and system event handling.

• AppDelegate.swift: Manages the application lifecycle.
• NotchViewModel.swift / NotchViewModel+Events.swift: Handles the state (counter value, popover visibility) and event logic (mouse clicks, app focus).
• NotchContentView.swift: Defines the UI for the counter and buttons.
• NotchView.swift: The main SwiftUI view for the popover.
• NotchWindowController.swift / NotchWindow.swift: Manage the custom, transparent window that acts as the popover.
• EventMonitors.swift / EventMonitor.swift: Handle global mouse event monitoring.
• main.swift: Application entry point.

1. Open NotchDrop.xcodeproj in Xcode.
2. Select the NotchDrop scheme.
3. Build and run the application (Cmd+R).

This project serves as a learning example or a starting point for building more complex macOS notch applications with SwiftUI.
