Maybe there a way to write a custom format in Edit->Preferences->Display->Name Format to display part of a Surname in the chart (Eg: Schwarzendruber as sh). I am not aware of how to do it.
My idea is a to print a chart with all members of a certain family along with 2nd cousins and their family names. Since there is not much real estate in the chart, I wanted to show a short family name with a legend on the side of the chart. This monogram helped, even though it may not be the most elegant way.
I haven’t searched for that. But it seemed like there might be too few Name fields in the Person object Help of SuperTool.
My big concern is that some Display Name customizations seem to have disappeared from Preferences when I switched repeatedly between Trees. (I switch Trees a LOT for testing techniques & tools )
