Appointments+ - remembering customers at sign up

I have a customer that would like to answer phone calls for appointments and input the appointment himself into the live calendar. He would like the plugin to remember all customers so that as he types in the customers name on the front end it pops up and he can click it. Is this function available with appointments +? Or is there an alternative way to do this?

Also when using appointments+ in the new spirit theme the name and email field do not show a window or area to type. It just looks blank, screenshot attached. Is there a way to have an enter field show up?

Thanks,

Chris
