Agreed . . . still, in 2018. I’d like to right-click document in book file, rename it to a new version number, and have InDesign keep the old file (not really change, per se) and have InDesign be smart enough to reestablish links to the new file. So while the book lists “Chapter03-v03.indd”, the v01.indd and v02.indd are still there as files not attached to the book. I can drag them to an archive folder with zero damage to the book or links within it.
A Finder rename and reattach to the book isn’t a great option because links from other chapters tend to retain their links to the pre-renamed file.
I also don’t need versions of the .indb file. While not a “100% perfect” version control system, I have no need for the old .indb files.
It’s been a while since I used FrameMaker, but I *think* that if the book were open, I could go to Finder, copy the old chapter off somewhere and rename the original, and Frame’s book does all the changes for me. I think…
