Option to force TidyCal to "always display at least X number of days of availabilities for meetings" even when weekends/long weekend come or vacations/seminars/several full "busy days" are booked on one's Calendar that prevent TidyCal to show availabilities.
This will allow the option of "How far out can users book? /Show availabilities X number of days ahead" to actually work as "Show X number of days of availabilities (always), by not counting full busy day (days with no availability, like weekends, vacations, full-day events, etc.)".
So we can either add that as a secondary addon option to the one we already have in TidyCal, or we can just remake the option "How far out can users book?" to "How far out can users book (not counting full busy days)?
