With regards to your appointment booking page system (big fan by the way!) there is currently no way to schedule in time off or annual leave (if using this system for professional/commercial use with clients).

The only way there seems to be to block out time periods is to create dummy events in your calendar that run from say 9am to 5pm, or whenever you have your scheduling hours set for...

Would it be possible to please create some kind of "I am off on these days" functionality for those of us who are using the scheduling page for our professional clients/work use?

Maybe you could add a button to "stop appointment bookings on this all day event" if someone creates an event that's longer than two days or something like this?
