Hi,

I was looking at this module here - https://drupal.org/project/term_ref_autocomplete. This has a great user interface for selecting the proper term from either parent or child, but it does not store the "term lineage"

I think, if you combine this HS and give an additional 'widget' for selection say - that would be awesome.

For vocab that goes say 2-3 levels deep, this would be a great UI improvement as user does not have to select parent, wait for child list to load, select child, wait for sub-child to load etc.
