I thought I'd seen something about this, once upon a time, but can't find it now.
I'm wondering if it's possible to find out when a given style in a given document was last defined and compare that with the same info for the same style in a different file. I thought the style comparison feature in Blatner Tools might do it, but after reading a bunch of descriptions and sales pitches, I'm still not sure if this is one of the things it compares. Haven't bought BT yet, though I will soon.
It would be cool if when I clicked the double-arrow-synchronize button on the book panel ID would warn me that style X in file N is in danger of being overwritten by an older version and ask if it's OK (like it does when synchronization will cause text become overset in certain files, or when I want to save a file with the same name as an existing file).
Or if the whole sync process had the option to use the newest version of each style as the source, regardless of which document it's in. Could cause nightmares with styles based on other styles, perhaps, but not if you're pretty conscientious about keeping everything equivalent.
While I am careful about this, I'm always paranoid that I might have solved some little problem with a character style in chapter 4, failed to sync that style in all the other chapters, then synchronized all the styles in the book with another file as the style source, wiping out the change in chapter 4 and not realizing it until it's too late.
Best option of all (for me anyway) would be to have styles that apply to a whole book (or a chosen subset of files within a book). When I do a book, I set it up so that every file has the same styles, and try to avoid having styles that exist in only one file or some files. I would LOVE it if I could check a box in the style definition that says “Make this a book style” and then have it move from the document's list of styles to the book's list of styles. Change it in any document and it changes in all documents instantly.
This seems so obvious that I now think something similar must exist in some form and I've either forgotten it or am just oblivious. Must be a plug-in for this, right?
Thanks.
