At one point you were excited about the idea of importing annotations from a file, but then seemed to become totally against it, pushing for pasting to the Document Grid as the only solution available to users. Many users have made it clear that they would like the option to import a file. And now, one has made it clear that he needs an option to assign annotations from the command-line interface.

I think it is time to implement the feature to allow annotation import from a file and enable its use from the command-line.
