Appointments+ feature request - ability to view & book from a calendar in admin

Feature request:

1. The ability to view a calendar of bookings from admin.

2. The ability to click on a date in the admin calendar to add/change/remove an appointment.

3. Or at the very least, the ability to see your schedule in a calendar view whilst adding new appointments from within admin. (calendar below or to side of appointments add)

These features would make the app even better. thx.
