Drag and drop both folders and documents
In Zoho Writer, I would love to organize projects by dragging and dropping folders and documents.
For example, I could have a folder for a story, a sub-folder for a chapter, and individual documents for scenes in the chapter. Then I could drag and drop to rearrange the order of both chapters and scenes.
This is now possible in the PageFour writing program for creative writers, which is Windows only. You could take a look at how they do it, then see how to do it in Zoho Writer.
