I have added a new project type to my fork of Doccano that support LayoutLM training data sets. This combines the BoundingBox and the Relation, and adds OCR for text bindings. I've completed it to the point where it's satisfactory for the project I am working on, however I am seeking permission from my company leadership to polish the UI to get it consistent with the rest of Doccano and submit it as a pull request back to the core project. Before I invest the time to do this, I want to check to see if this is something that the community would like to see added to the project.
