I really like the default Airmail setting where the app it self is small and stays in one corner of my desktop, and when I have an email, double-clicking it will open it in a new window just for the email, rather than in a pane on the main window
This allows to have my email app neatly on one side of the app, and to check multiple emails at the same time
I know we can “pop out” one email to view it in a separate window, but I’d like a setting where the “viewing pane” in the main window disappears, and emails are automatically shown in a new window
