This is not a major problem. It’s more of a quirk.
I can highlight a half-dozen empty folders and export them as a template.
Actions → New from template → my group template will then plop a copy of the group structure in wherever I’m sitting in a DT database. Very cool.
However, if some groups are subgroups of others in the exported template, the import has a funny quirk.
The subgroups appear in the structure where they should be, but also appear as replicants at the top level of the templated group.
Should a group template create new replicants?
