Add a "Bookings snapshot" for week or month that shows booked hours and remaining available hours.
It would be really cool if I could see at a glance a summary of the hours or appointments booked and how many are left available for each employee and the business overall. Example, this week Joe has booked 15 out of his 30 possible appointments, 50% full, for a total of X hours. And the business overall has 40 of possible 120 appointments booked this week, 30% for a total of Y hours. Then icing on the cake would be that Joe is responsible for Z% of the bookings.
