It would be great to be able to drag schedule items around in calendar view it change item start times and durations.
When creating a schedule item it would be awesome to be able to double-click on the calendar view at the time you want the item to start so the item creation pop-up picks up the start time.
It would also be great to be able to manually input the times (in 12h or 24h format) in addition to the scroll wheel available.
