@copilot Here is the original Jira issue for this change:

=== Start Jira issue ===
Title: Inform users which chapters will be overwritten on draft import
Description:
Currently the draft import dialog states how many chapters have content (see screenshot), but not which chapters have content.

Enumerate the chapters that have content
Make each chapter number a link (that opens in a new tab) to the chapter in SF, so it's possible to see what would be overwritten. Feedback from users has shown that sometimes the "content" is minimal and in a user's mind wouldn't be something they should be concerned about overwriting.
Change the intro text to something like “Click each chapter to view the content that will be overwritten”
=== End Jira issue ===

Please do a code review and a functionality review.

It seems to me that we've lost a significant amount of clarity by going from specifically stating that there are chapters with existing text that will be overwritten to just saying "Overwrite ?" I know technically we're overwriting the entire book, but from a user's perspective they're doing an import, probably not expecting to overwrite anything. We should be extremely clear in why we are stopping to ask an additional question.

Sorry about the Copilot commits. I've reverted them (I was trying to get it to review, not make changes).

I think you may want to re-read the issue description.
