Can I search for client or customer appointments
Yes, if you open up the client contact card, then click the "more" button, under the "save button" then select the "appointments" tab it will show you a list of all the appointments for that client. Then you can keep that window open and navigate to the appointment date and open it there, then if you want to move that appointment, you can open the "more" button in the appointment window and choose the "move" tab and move the appointment that way....
We are hoping that in a future release, you will be able to click on the list of appointments in the contact card and have it either navigate to the appointment and/or open the appointment up direct from there.
