@kovidgoyal --

A thought occurs (sometimes I get lucky)

If I have an epub with inline comments, and I use the planned F&R capablity to apply changes (leaving the original comment but inserting its calculated value) would I be able to re-edit the original document?

For example if I use the F&R to insert chapter numbers and then rearrange the html files (invalidating the chapter numbering) would I be able to edit the original epub and re-replace and get an updated chapter numbering?

It might be worthwhile to consider allowing some very simple inline comments that are resolved into actual values
