Drupal has powerful tools, like draggable views, for managing hierarchical trees, but when the number of rows exceed, say a few hundred, draggable views may become a bit cumbersome and slow. Moving several hundred of rows from one place to another or indenting or unindenting them etc. can be hard or it can even be impossible due to the memory consumption of the browser.
I've created a small module for my own use, which offers the titles of the whole tree in a form textarea field as tab indented text, which I can copy-paste to my favourite code editor and use its ability to move, indent and unindent hundreds and thousands of rows easily. I can then paste the edited text back to the form and hit save. The module then takes care of reorganizing all the nodes of the big tree.
I don't know if the use cases for this would be numerous or rare. I could imagine that someone managing something like a scientific taxonomy or large product database could use this.
What are your thoughts, would this be of use to someone?
