This is very interesting and a much needed tool. I have been searching for a tool like this for a long time. There are so many tree-like structures that I'm sure there will be interesting use cases...
I was recently working on a similar tool[1] but specific to the domain of "content trees" that consist of content nodes organized into a hierarchical structure. In my case each tree node has a persistent `content_id` associate with the underlying content file and independent of its position within the tree, which allows me to detect "move" operations[2] (a node with the same `content_id` appearing in a different place in the tree).
The use case is for educational content: Kolibri channels[3] are these huge trees that consist of thousands of nodes and it's difficult to know what has changed when we create new versions of the channels. I tried all kinds of general-purpose diffing tools and failed miserably so I started working on treediffer. It's almost done; I hope to finish it later this fall, and will look at graphtage to see how it works.
