Long, variable-length documents like books require the ability to add pages of a particular layout, such as odd/even pages, chapter pages, etc, making templates a less than ideal approach. While I can apply a masterpage based on odd-even, the content is a static background that cannot be edited. Would it be possible to allow the user to mark frames within a master page as being editable, meaning that their content can be changed, but not the size or location? This would allow the user, for example, to place a text frame at the desired locations on master pages for odd and even pages, then fill them with the desired content. Apply Master Pages already has the ability to apply just to odd or even pages, so that part is already there. Based on another topic, I know there is a variety of workarounds to this problem, but this is an essential feature of a book layout process, so it would be nice to have a smoother approach.
And if I'm being really greedy, it would be great if the master page could be dynamically linked to the page in the sense that if the page changes from odd to even (because of an insertion or deletion ahead of it), the master page is swapped for the corresponding page. This would require that master pages have a sense of being even or odd and are paired so that the swap can be made. Of course, the paired pages would have to have to have corresponding frames to allow the remapping.
