Is there a way for authors to number chapter 5 of part 3 as 3.5? I find it confusing when the update stream reports a new chapter posted with a lower number than I know I've read! Also, when responding to an author (using the feedback button at the bottom of the chapter) the title of the message does not indicate the part number, just the chapter wirhin the part. (I find it much easier if no two chapters in a story have apparently the same identifier.)
Of course, ir would then be up to authors to make use of the new facility. However, when they get feedback, lack of ambiguity about which 'chapter 5', say, is meant shoyld be worth something!
