The name templates section of the documentation is not clear / is confusing. In general 'name templates' is not clear at all unless you already know what it is. See feedback below for improvement, definitely in the documentation and possibly in the TUI / code:

"I would make the purpose of the templates clearer in the title of the section. Both words "name" and "template" are super-generic. Maybe "Customise validation" or "Advanced validation" or either of these followed by "using name templates"."
