i agree. in the meantime i have solved this by automatically  
populating a list field of a code source with the appropriate data.  
e.g. i have a list field with size 1 and in the tales of items i have

  python:form.get_forms()

get_forms() is a python script in the content of the code source with  
the content

  container = context.aq_parent
  return [(item.getId(),item.getId()) for item in  
container.objectValues(['Formulator Form'])]

this returns a list field where the user can choose form all  
formulator forms stored within the code source. another example is

  python:form.get_folders()

and

  tree = context.get_container_tree()
  return [(item[1].absolute_url(),item[1].getId()) for item in tree]

this returns a list of all folders in the context of the silva  
document where the source code has been placed.

now, what keeps you from collecting all assests (get_assets()) and  
filter out your desired assets according to their mime type  
(get_mime_type()). but keep in mind that images have no mime type,  
you need to take care of them.

granted this is not as nice as a lookup window but it is more  
convenient for the user anyway ;-)
