The Individuals Tab
This tab lists all the individuals that have been loaded from your GEDCOM file.
You can set the Root Person, ie: the person from whom all relationships are calculated, to anyone in this list by selecting a person, and then right clicking, and then select the option "Set as Root Person". A small summary report is then shown to confirm the change and to display how many of what type of ancestors you have.
By clicking on any column title, you can sort on that column and clicking on the column heading again will change to a descending sort.
The Budgie Code is a method of defining relationships, and some further explanation on how the code works will be added here later.
