If you have multiple instances of the Calendar open (multiple tabs, windows, or computers), and you make a change to an appointment in one it's automatically updated in the others.
Changes to Work Orders in the Calendar are automatically reflected
Changes to Work Orders that are automatically reflected in the Calendar include: Everything: day, date, time, tech, status, adding/removing a service...
This is perfect for those of you who have more than one person at a time managing the Calendar. No more refreshing the browser.
