 	offer to move parent/child series orders as well to match (think Thomas Covenant)
 
 ### TODO: 
+	- consider created/modifed for all fields? but mostly are they set via ORM for new books?
+	- need to delete 1 sub_book from book
+		* swap the 'add sub book' for 'remove from parent book' button and then act on it (separate route, simple sql exec and route back to (no-longer) child book) 
+			(noting that deleting a child book already removes the book_sub_book_link)
 	- when remove a Parent book from a series, what do we do?
 		(remove all sub books from series too?)
-	- need to delete 1 sub_book from book
+	- need to delete all classes (and watch for referential integrity)
+		* book (as long as no sub-books)... 
+			NOT tested how this goes with deleting book that is in a loan, or book that is in a series
+		- can delete:
+			author, publisher, series, condition, covertype, owned, rating, genre, loan, 
+	- should deleting really just ask if want to mark it as SOLD?
 	- need to add books to loan (on loan page, and via a book search?)
 	- need to delete book from loan
-	- need to delete all classes (and watch for referential integrity)
-		* book 
-		- can delete:
-			author, publisher, series, condition, covertype, owned, rating, genre, loan
 	- show books on shelf list
 	- show books to buy view / printable
+	- show unrated books  (with toggle to exclude those with missing in a series)
+	- show books missing from a series (I own only some of them)
+	- show books on wish list
+	- show books that need replacing
+	- show books I have sold
+	- show books with poor rating
+	- view list of possible duplicate books by title
+	- consider which of the 'books maybe not valid' reports make sense still
+	  (can you even have an N/A publisher now for example, but the genre one is interesting)
+
+	
 	- with ORM: should I lazy load all books (ajax the 2nd->last pages in, or not use ORM, and do a quick db.execute()....)
