     * need to use ORM for all bal, bsl, etc.  seems to be causing race conditions and or 'timeouts'
 
     - sorting books on shelf.  Up to Dune books --> is there an overarching series needed, and do it :)
+
+    * if we add a new parent book with sub-books into a series, with parent * book as 'null' sub_book_num, all the sub_books should be added somehow into series - but cant input numbering on parent book, so
+        - don't allow adding parent, use a pop-up saying, add the first-child, and then auto-number from there
+
+    * remove all non-ORM CRUD:
+        - grep 'insert into' *.py [DONE]
+        - grep 'delete from' *.py [DONE]
+
+    * consider removing all direct sqls and using ORM properly:
+        - grep 'with db.engine' *.py
