Drag & Drop Rescheduling

[thebundok]

If I've planned out the year but something comes up where a lesson must be rescheduled it would be nice to have the ability to drag/drop that lesson to a new date as well as have the other dates shift to the next week(s).

OR

If I change a lesson using the current method and it matches next weeks lesson, it would be great to get a confirmation box asking if I would like to adjust all subsequent weeks accordingly.
