The software screen layout consists of three panels. The top panel holds the domain names and various extracted information in a neat table. The lower panel holds the actual raw whois data for the domain that is selected in the top panel. A left vertical panel displays a domain pad that is useful for holding domain names that interest you (sort of a scratch pad) as well as a lookup queue. The following screen shot will make it very clear.
The panel sizes may be adjusted by using the mouse.
