Clarification for "term settings"

Hi,

First of all, many thanks for this great module, it's a marvellous piece of idea and work!

Only thing I need is a clarification on the "term settings". I would have thought (from the module's help) that using these, I can set the fields for all subterms. For instance, if my taxonomy looks like this:

• document
  • text document
  • worksheet
• image file

then I would have thought that using document's term settings, I could assign the same fields that are assigned to document to all its children (i.e., text document and worksheet).

What exactly does it help me to see the ancestors of a term?

My hope was that I can click a checkbox "Assign assigned fields to all subterms"; then, even if in the future I add a subterm, all subterms would have the same fields as the original term.

Looking forward to any feedback,

Thanks,
Kaspar
