The Miscellaneous branch under Configuration - Toolbars/Menus has the following options:
Number of recent files on file menu
This setting sets the number of recent files that appear on the Application menu for quick opening of files.
Recent files list on file menu
This option configures the recent file list to appear on the File menu rather than as a submenu of the File menu.

If this setting is changed, the application will have to be shut down and restarted for the change to take effect.
