There needs to be more intelligence behind the way the system blocks renewals if there are existing holds on a title. When this setting is enabled, renewals will be blocked even when there are other available copies in the system. For example, if a patron tries to renew a copy for a title that has 20 other available copies, but just one hold, this renewal will be blocked. Enabling this setting should only block the renewal if there are no other copies available to fill the hold. Staff should also be able to override this as needed.
