{ previous_document } as a plugin variable

As part of Chapter Continuity, there is now a variable being used behind the scenes that represents a single linked document that represents a previous part of the story that the user wants to include in the prompt when generating the next bit of prose in Write or Draft.

I’m requesting that this variable be exposed in the plugin creator tool when Chapter Continuity is released. This will allow plugins to fill a variety of workflow gaps (for a variety of workflow styles) that will remain when Chapter Continuity is released.
