Reviewer's Guide by Sourcery

The PR modifies the close behavior on macOS by using SystemNavigator.pop() instead of appWindow.close() to properly exit the application when the close button is clicked in the tray menu.

Hey @XMLHexagram - I've reviewed your changes - here's some feedback:

Overall Comments:

• The PR title mentions tray menu behavior but the change affects the general close manager. Could you clarify the scope of this change and whether it's specific to the tray menu or affects all close operations?
• Consider using platform channels or native macOS APIs instead of SystemNavigator.pop() which is primarily designed for mobile applications. This would provide better integration with desktop-specific behaviors.

Here's what I looked at during the review
