When working with a case, you can view the calendar for just that case to see its scheduled timeline of events. And just like the regular calendar in ParaLaw, you can view the appointments for other firm members, and also show two or more calendars side-by-side. If you need to schedule an appointment, click the "Show All" option to see all of your appointments to see when your schedule is open.
