Hello,

I am developing a booking system where it is useful to see when during the day the booking begins. Most bookings are for the night, so if the booking looks to be during one day it is misleading since it actually spans two days, but one night.

But this is not always the case, some bookings can be for the day, ie. 00:00 -> 23:59.

It would be great if this could be reflected in the scheduler. The look i am after is something similar to this:
