One click to appointments

I would like to be able to click from the client card straight to their appointments. Some times a client will call in and ask when their next appointment is, I can look them up by name and see all their upcoming appointments, but then I have to exit out and go back to the calendar to find their appointment to make any changes. It would be nice if we could click from the client card directly to the appointments on the calendar or their invoices. One less step.
