Could we have an option where in the open hardback with dust jacket shape the front and back jacket flaps width can be modified? At the moment the width of the flaps is set. There is an option for the hardback with dust jacket shape (the closed book) but not for the open one. As most publishers / designers will tell you they tend to vary - sometimes flaps are really wide - 110 mm or more - sometimes less than 80 mm in width. Thanks!
