A cool new feature would be if each appointment could optionally be assigned a corresponding section in the Moodle course, which would then be automatically highlighted in the Moodle course. This means you don't have to manually control the highlighting of a section in Moodle. In order to continue to enable manual highlighting, there should be an adjustable lead time in days from which the highlighting applies (default: 7 days). For recurring appointments, the assigned section must be adaptable for each repetition. This should already be the case with the existing overwriting options for individual appointments.
