I should mentioned that we will be adding options to display numbering in the editor group views (not the binder). These will be “dumb” numbers in the sense that they count all of the objects in the view and put numbers in front of them, starting at 1. So if you click on Chapter 53, the first subdocument in the chapter group would be “1”, but if you click on the entire Draft and view it as a large outliner session, everything in the draft would be counted sequentially.
If every numbered item in your Draft folder will be compiled in one form or another, and all levels of the outline use the same numbering scheme, then some basic numbering tool like I described above may be good enough. Actual compile numbering however does have issues that are intrinsic to the design of the software. If you want to look over some of the reasons, here is an older post with some explanation of the various difficulties posed by a system that is designed to produce fully numbered documents through some lengthy export process.
