The OpenStep Defaults system, for example, allows hierarchical  
specification of defaults, very similar to preferences.  There is a  
global level which is overridden by a per-application level which is  
overridden by a per-process level taken from the command-line.  The  
first two levels are stored in a per-use defaults database.

A Squeak per-image level would have to be inserted between the  
document and process levels as a "document" level.
