To toggle between different viewing preferences, select Preferences from the File menu and then click the Interface tab. If you want to see multiple windows for the same module (side by side or above one another) click on the check box that says "Allow opening multiple windows for the same module." If you wish to display only one window for each module, leave this check box empty.
On this page you also have the option of automatically displaying the icon views for each item you have in your Items table. This feature allows you to confirm that the items you have imported were in fact imported correctly. To turn this feature on, simply click on the "Automatically display views in items list" check box.
