For a macOS app, if you want an action in both the main menu and the UI, it's quite boilerplaty. You need to synchronize some value with @focusedvalue. What if we had something like this?

SwiftUI Placeholder idea.swift

struct CameraCommands: Commands {
	var body: some Commands {
		CommandGroup(replacing: .newItem) {
			// This menu item will be enabled when the key view has a button with `.command(.takePhoto)`. The action logic is implemented in the button.
			Placeholder("Take Photo", id: .takePhoto)
			
			// Alternatively, it could be:
			// Button("Take Photo") {}
			// 	.placeholder(.takePhoto)
		}
	}
}

// ...

struct MainScreen: View {
	var body: some View {
		Button("Take Photo") {
			// Logic here
		}
			.command(.takePhoto)
	}
}
