Schedule Items - Drag to move and manual times entry

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.
