In a number of places, I can make changes but have to select update to make them stick. If I forget and leave the screen, the changes are silently discarded. I propose a query something like "You have made changes to this item. [Update Changes and Exit] [Discard Changes and Exit] [Return to Editing Item]". This is comparable to Wordpress asking whether I want to leave a page or remain on it when I have made changes to it.
