Aargh! We REALLY Need Undo for Binder Drag/Drop

Just now I dragged/dropped a scene in the binder. I didn’t realize that I had five scenes selected (long story, but it wasn’t obvious), and as a result, all five scenes were moved to the new location! Now I have to guess where they were before. I could go to a backup, but that’s more radical than I want.

An undo would have been appreciated. Please put that on the list.
