Having multiple drawings open and switching between them has always been a fairly simple task. With PostalCAD 2009, a new method has been presented for switching between open drawings.

Click on the large blue M in the upper left corner of your application window and select Open Documents from the bottom left area.

In the upper right corner, select the icon to set the view properties to Large Icons.

Now you can hover your mouse over the preview to get more information, if needed.
