Specific appointment times
It would be great to be able to input specific time slots on the calendar that are available for online booking. I find the option of 15, 20, 30 or 60 minutes frustrating. For example, if I select 15 mins and there is a slot available between 9am and 9.40, someone can book in at 9.15am which means I have 15 minutes of no client at the start of the day and by the end of the day I will have lost the opportunity for at least one extra appointment. Being able to control the exact times people can book in would be really great.
