It will. Every call to qof_book_not_saved automatically calls 
qof_object_is_dirty which checks each collection in the book for the single 
boolean value in each collection and returns TRUE if ANY collection is dirty. 
The collection will (with the new code) be marked as dirty as soon as any 
entity in that collection is marked as dirty.


It's fast because it's only checking a single boolean flag in each case and 
there are only as many primary collections as there are registered object

That can be arranged - Derek mentioned enhancing the event handler and the new 
function provides a home for the call you need.
