Unscheduled events

[vukadinFE]

Is your feature request related to a problem? Please describe.
We are using the drag-to-create plugin and we love it. However, it would be perfect if we could move events out of the calendar to "unschedule" them.

Describe the solution you'd like
Either have a new plugin for example drag-to-remove or one combined plugin that could have an additional "unscheduled" box where you could move from/to events.
