Directly from LMSCloud's requirements: > As a Koha library, we want to be able to use configurable additional fields for bookings in order to enable patrons to provide additional information with bookings like the persons who need to be informed when the material is available or a contact person of the institution. > The additional fields will be editable and stored with the booking and should be also available in booking notifications. I think this is interesting because these use-cases seems like a perfect fit for the bookings feature. For example when working with schools or something of the like.
