Hi, 
thanks for your plugin, it's really easy to use and I'm trying it with a limited number of customers before adopting it. 
One things that has been often reported is that a customer doesn't know the status of appointment request submission while it's been performed.
I.e. when he selects a data and fills in all the needed information, he eventually presses the submit button. 
At this moment, there's no wait cursor indicator (like hourglass) meaning that the request is currently ongoing. Is there the possibility to add an hourglass or something similar to make the customer aware of the request in process?
Thanks
