WFTB allows you to display sosa numbers (or not) in your family tree.
The basic setting set by default when editing a template does not display sosa numbers. If you don't want to display them, you don't have to do anything.
The sosa numbers can be placed in four different places in the individual blocks. top right or left, bottom right or left.
You can change their appearance like any element in the tree.
To configure the sosa numbers, simply click on the "Texts" button in the menu, then go to the "Sosa number" tab, then adjust the settings on the interface.
