USFamilyTree is working on a new version of the Advanced Tree Inspector that will work with the FamilySearch Family Tree.
The new application will be available February 2014. Thank you for your patience.
Internally, we've used the Advanced Tree Inspector tools, among other things (like Ancestry's censuses) to create family indexes on a bunch of US surnames. These indexes are like a skeleton, or basic outline, of the entire surname group.
You can use them however you want, but the most effective use would be to complete the descendancy group by filling in all the remaining data, individuals, and family relationships to create a complete descendants group then submit them to new FamilySearch, OneGreatFamily, Geni, or another world tree for everyone to enjoy, or create and host your own online family tree software.
