You are right about it looking good for menu items. TransferMorph 
specifically aligns its bottomLeft with the hand, thus keeping the text 
fully readable.


aboutToBeGrabbedBy: aHand
     "The receiver is being grabbed by a hand.
     Perform necessary adjustments (if any) and return the actual morph
          that should be added to the hand."
     "Since this morph has been initialized automatically with bounds 
origin
          0 at 0, we have to move it to aHand position."
     super aboutToBeGrabbedBy: aHand.

     self align: self fullBounds bottomLeft with: aHand position.
     aHand newKeyboardFocus: self.


The above could be changed to #topLeft and perhaps achieve the effect 
you wanted, although maybe less nicely for menu/list items. I was 
thinking that since TransferMorph was making things a bit difficult, 
maybe TransferMorph could clean things up. Have you installed a 
transferMorphConverter in the World? What does it do? Maybe that's the 
place to handle the offset.

morphToDropForTransferMorph: aTransferMorph
     "aTransferMorph has been dragged directly onto the desktop. 
TransferMorphs, by nature, are about transferring a 'logical object' 
from another source. Answer the Morph that should actually be dropped on 
to the desktop."
     ^ self
         perform: self transferMorphConverter
         with: aTransferMorph
