Issue #407 https://developer.apple.com/documentation/appkit/nsworkspace/1524399-selectfile In macOS 10.5 and later, this method does not follow symlinks when selecting the file. If the fullPath parameter contains any symlinks, this method selects the symlink instead of the file it targets. If you want to select the target file, use the resolvingSymlinksInPath method to resolve any symlinks before calling this method. It is safe to call this method from any thread of your app. NSWorkspace.shared.selectFile( url....

Issue #403 https://developer.apple.com/documentation/appkit/nsapplicationdelegate/1428381-applicationshouldterminateafterl?language=objc The application sends this message to your delegate when the application’s last window is closed. It sends this message regardless of whether there are still panels open. (A panel in this case is defined as being an instance of NSPanel or one of its subclasses.) If your implementation returns NO, control returns to the main event loop and the application is not terminated. If you return YES, your delegate’s applicationShouldTerminate: method is subsequently invoked to confirm that the application should be terminated....

Issue #332 From moveItem(at:to:) Moves an item from one location to another in the collection view. After rearranging items in your data source object, use this method to synchronize those changes with the collection view. Calling this method lets the collection view know that it must update its internal data structures and possibly update its visual appearance. You can move the item to a different section or to a new location in the same section....
