Allow different hours on different days
Have different hours on different days. Like Wednesday 6-9, and Sunday 10-5.
Allow all day event bookings
For example, if guests can drop in a space anytime between 8am to 5pm. Instead having the guests select a specific time slot, once they select a day, they immediately land on the intake form.
Set limit by appointment type in a package
We can set the total number of events in a package, but there's no way to explicitly say, x of this type and x of that type. My example here would be in a consulting package, the client gets 4 long meetings and 6 short meetings and there's no way to have the system police that.
Allow guests to select from multiple event durations
E.g. Choose one of 30min, 60min, 1 hour 30 min, etc.
Add ability to set a timezone when setting availability / scheduling
I travel a lot for work and it'd be nice to schedule when my timezone will change.
