To modify how Design Console arranges multiple open editors:
In the Window menu, click Arrange.
The Arrange dialog displays six different editor layouts as buttons. Click any of the buttons to apply its displayed arrangement to any currently open editors. The editor numbered 1 represents the most recently selected editor.
Click Apply to implement and view the new arrangement. To try a different arrangement, click another layout button. When you are satisfied with the layout, click Close.
Note: The Arrange option is available from the Window menu only when at least one editor is open.
