English isn't my first language, so please excuse any mistakes.
Well, let's take a look here: Context Menu --> 'Save Attached File(s) To...'
I think this menu item should be disabled for multiple selected entries (2 or more) when they have no attachments (see how it works with a single entry). Now this feature allows us to save files (even those that do not exist) to needed location. Thus, the result is only an empty directory. Some users may be surprised by such behaviour, especially if they are not sure whether there really are any attachments.
