Stop Folders Auto Opening

Is there a way to set the folders in the binders to refrain from expanding when something new is dragged into them?

No, I’m afraid not. They do that so that you can see exactly where the dropped items go…

Well consider that a feature/option request. Drives me absolutely batty.

This sometimes bugs me, too. Maybe what I’d like to see is a hidden preference to change the delay before spring-opening the folder.
