Hello robin.

1. If you need to add special working hours for only next Wednesday, you need to go to your employee's profile, and under Special Days add a special day, where you will define working hours with the 30-minute break. Please note that the "default time slot step" in General settings needs to be set to 5, 10, 15 or 30 minutes for you to be able to select a break this long.

2. I'm not sure I understand what you mean. If you have cancelled an appointment, you can either edit that appointment and add a new customer from back-end, or you can create a new appointment at the same date and time for another customer. Which version of the plugin do you have?

3. Unfortunately not yet. Our developers do have that planned for the future, but I cannot say when it will be included in the plugin.

4. You need to go to Appointments, and choose the date range:

Then, below the "New Appointment" button, click on the export icon:

You will see a list of fields that can be exported:

At the moment this is the only option for exporting appointments.

5. You cannot, the available time slots are calculated based on your employee's availability, and there's no way to preselect starting times.
