When I'm trying to clean up a project, I find myself taking a screen capture of the Library Information dialog, so that I can remember the items I'm going to hunt down later. A Copy to Clipboard button would be a tad more useful - I can paste the list into Notepad as a memory jogger.
But the next step beyond that would be to make each item in the list clickable to take you straight to the item(s) with the missing data.
