Admin should be able to set whether user need to select location if business have multiple outlets.

User should be able to use just phone number for booking.

There should be option to send SMS confirmation as well as SMS reminder to user and email confirmation to respective party as calendar list end of the day rather than individual booking.

It would be great if has API to transfer book schedule to relevant application for detail for person name information.

Much need to be improved. It seems very basic now.
