Thanks to Rob who wrote to me requesting more options in notifications such as archive, trash and reply inline.
Currently Aura just fades the notification in and you have to open the main window to do anything with the message.
Mockup below as an example.
One consideration is that it is not possible to have banner style notifications (vs alert which does not fade away) on Mojave without using private APIs.
Aura isn’t distributed through the App Store, so using private APIs isn’t a dealbreaker, but I’m going to verify if there is a better way and will keep updates posted to this thread.
