A really great way for your operators to view their clients histories, and make new notes on the current days appointments, is to print off the Operator Day Card for each operator. That way your operators can take their print off around with them during the day and use it to refer back to history notes. They can also scribble down new notes which can be entered into the Simple Inked Appointment page later on that day.
Viewing the Operator Day Card.
Click the operators name at the top of their appointment column.
In the pop up window, click Print Operator Day Card.
The print off will display the operators appointment column, with all of the days clients and appointments, plus the clients past few appointments including history notes.
Your operators can take this round with them to refer back to, so that they don't have to keep checking back on the computer.
