So I tried to summarize it in the title.  I am having trouble with my appointments because, first, the calendar shows availability starting the same day the appointment is being made.  Since I get appointments from many timezones (London to Sydney and anything in between) this is a real problem, because people book to soon or when it is impossible for me to fulfill the appointment.  Not that anything is bad with this plugin, I LOVE IT! So far it has helped me a lot, but I would love to know how to do this change: To show my availability starting the next day so I have enough time to fulfill the appointment.  And also, I need to show only certain available hours to people depending on their timezone. For example: 3:00PM to 8:00PM-only for people in the UK, so that they book me at times I am actually available or 8:00AM to 12:00PM-only for people in Australia.  And also adjust according to current timezones within Canada and the US.  I believe this is not very difficult because Geolocation can be the variable that defines this but I have no idea how to do this.  Could somebody implement this into the code of the Easy Appointments plugin? It would help me tremendously!  I have also thought of other appointment plugins but they are not free, they go from 30 to 60 dollars and I would rather pay you guys for this customization.
