Currently, the calendar widget displays the complete day from 00:00 to 24:00. If you want to use the calendar for planning during working hours, it would be very useful to be able to limit this to eg 08:00 to 18:00 (configurable). This should be available for day, week and workingweek views. In the current widget, if you have back-to-back appointments that are less than 20 minutes long, they overlap (with regular resolution and zoom levels). This makes it harder for users to select the correct timeslot.
This would be a very useful enhancement!
Very good idea!
