The main window is the window that appears when KMail is started. It is by default divided into three panes:

The messages contained in the folder will now appear in the Headers pane. The folder list can be displayed in both a short view, which takes up only a small portion of the left side of the screen, and a long view, which takes up the entire left side of the screen but is able to show more mailboxes. You can toggle between these two views under Using Folders section for more information about how to use folders.in the dialog.
