Would I pay $40 for a beta release? Definitely not! Family is far too restrictive in the kinds of data you can enter about people, and far too proscriptive in the ways people can relate to one another.
Dragging one person onto another creates a nauseating <heart> icon to indicate a 'relationship' - and there are no preferences so, for example, UK users are forced to enter dates using US formats, even though system-wide preferences are set to use UK formats. Males are automatically coloured blue and females pink and there is no way of changing these stereotypical settings.
Clicking zoom family brings up another window which completely hides the main window. Adding a new person is done in the background window, unseen - and the zoomed family window does not update.
