Show "City" field in appointments list

Hi,
When I click on Appointments menu, the plugin shows by default a list of all Active Appointments.

3 Questions:
1. How to display the appointments list sorted by "Date/Time" by default.
2. How to display the "City" in the list.
3. How to sort by ID, Client, City, Date/Time, Service, Provider, Status. (a clickable sort button will be great).

Thanks.
