When you go to delete a folder or file on dropbox it has a message that asks if you are sure you want to delete...but when you go to move a folder to a different location there is NO warning message. This has happened a lot where someone accidently drags a folder to a wrong location and would be prevented if there was a warning message that made sure this was a move you wanted to make. This should also be the case if you are trying to drag a whole folder out of Dropbox to avoid an accidental move that the user is not aware they are making.
