Calendar suggestion: drag-and-drop delete?

Deleting old events from past months, it occurred to me that a drag-and-drop feature for this would be great.  Maybe a trash can?  This would save one having to click each event, Mange Event, then delete.

Also, if one saw an event on a calendar that became a repeated (e.g. weekly event), what if one were able to drag and drop it to another day and then have a small menu pop asking you if you want to simply copy/move the event to that day OR have it become a repeated event?  Just thinking out loud..
