I cannot change the section type of a document from a custom type to structure based either in the inspecter or via the outliner. It reverts back to my custom section type.
Also, when using structure based formatting the draft folder is set at level 1 so to get the correct formatting you have to add an extra level to take account of this. So documents and folders within the draft folder are recognised at level 2 rather than level 1. Is this intentional, or a bug?
