Aha. Then I definitely recommend Notifications. Take a look at  
subclasses of OBInteractionRequest. OmniBrowser uses them everywhere  
it needs to initiate interaction with the user - basically for opening  
a menu or window. As a result, the same core code can work unchanged  
with Morphic, a web UI via HTTP and a fake UI that's used for testing.

Cleaning up direct use of Morphic in Squeak is a worthy goal - please  
share the code with us. I can certainly use it even if it doesn't go  
into the main distribution. Here's a fix to Parser to get you started.
