Hierarchy management solution(s)? (node or taxonomy) I have a content type with a large number of nodes (70K+) and have integrated a straightforward, though custom, node hierarchy solution (node reference for the parent, sibling order using delta).

I'm implementing a custom hierarchy management tool and have started out playing with taxonomy because the hierarchy management is already present (drag &amp; drop). However, core's default taxonomy management only goes so far, and though a good starting point, will not be suitable for a vocabulary this size (moving a large piece of the tree somewhere else isn't possible, as the vocab is paginated).

I then thought about a view combo'd with VBO, and a few custom actions, but i'm not sure drag &amp; drop could be used with this method.

Question:
Have you used (or seen) a drag &amp; drop hierarchy management solution (node or taxonomy) implemented either in views or a contributed module that fits this scenario?
Yes, the wonderful Taxonomy Manager module. I don't start a big project without it these days:


  This module provides a powerful interface for managing taxonomies. A vocabulary gets displayed in a dynamic tree view, where parent terms can be expanded to list their nested child terms or can be collapsed.


It's packed with features, there's a list of them on the module page. I think this one in particular will be of interest to you:


  Double Tree interface for moving terms in hierarchies, adding new translations and switching terms between different vocabularies
