By the way, there is a bit of cross-feed with another thread I just posted in, wherein I described a way of backing up the order of the binder, that might of be interest to those in this thread.
It does require one to be a little pro-active, but it’s a small task all around; a few clicks for some peace of mind.
First, follow the instructions in the upper portion of this post, to create a linked and indented list of items in your binder as it stands.
Proceeding from that point, take a Snapshot of the link list (Ctrl+5 / ⌘5). You’re done for now. You have a redundant hard copy of the list in a snapshot that cannot be accidentally messed up.
Now as a test, move an item or two around in the binder and repeat the procedure of creating a link list of the whole draft, pasting the result into the same document, updating the main text.
Use the Navigate ▸ Inspect ▸ Snapshots menu command (or however you prefer to get to that place in the inspector), select the snapshot representing the initial state of your binder, and click Compare. I would suggest changing the comparison mode to “By Paragraph” in the option button to the right of the compare button.
A line marked as an addition is where the missing document was moved to, and the line marked as a subtraction is where a document was moved from.
The only real downside is that it is something to remember to do after you have made any real changes of substance to the binder order. It’s a less than critical downside though, as the side effect of not remembering to do this often enough just means there will probably be more change lines to jump through and disregard as intentional edits, either to title changes or shuffling the order on purpose. You’ll still find the error, in other words, it just won’t be the only two lines in the comparison view.
But for those that make a habit of it, this technique would also be of general interest in seeing how your binder order develops naturally over time, as well, with a sequence of snapshots taken at notable points of revision. I.e. it doesn’t just have to be a recovery tool, it can be useful for seeing how the work is proceeding.
