The home tab is a quick starting point for most of the stuff you'll want to do.
Tabs
Click on the big tabs to get access to the main sections of the program. You can set your search criteria and location, and when the scan is complete results tabs will be available.
A Profile is a 'snapshot' of all your current scan settings, criteria, and scan locations. You can use these saved profiles to quickly recall different scanning scenarios.
Note: Some application wide settings, such as logging and caching, aren't saved as part of the profile.
