I love that when in the "chart" tab the therapist can easily see the client's appointments for the month (arrived, failed, scheduled) as colored boxes on the calendar in the top right. It helps us tell at a glance how often the client has been coming, when their last visit was, when their next visit is, and how compliant they are! It would be very helpful if this kind of calendar were visible on the "Schedule" tab when you have a client selected. (eg, click on the current appointment of the patient you are wanting to schedule and you get a good idea of their frequency and preferred days in order to schedule more appointments).
And it'd be nice if they brought back those 3 circles (arrived, failed, scheduled) on the appointments label on the sidebar when in the patient's note.
