There are five tabs on the Organize pages, for GEDCOM info, Family info, Numbering info, Tag info and Report info:
Press the "Save" button at the bottom to save all this Organize info into a Behold Organize file with the suffix: .bho
No data is saved. Each time you open a Behold Organize file, Behold will load the the Organize Information back in, and will follow that by loading the GEDCOM files specified on the GEDCOMs page which contain the data. Then the Everything Report will be organized according to the Organize Information.

Behold gives you the capability to separate the genealogy data itself from the specification of how to organize it. I hope you make the most of this.
