Yes! The manuals give a good idea what the package is doing.
The simple abstract example in the Core manual is helpful
because it is so simple. In the Queueing manual and in
the package itself you give some more elaborate examples.
- TelephoneConnectionSimulation
- ComputerSystemSimulation

Simulation is an area where Smalltalk is aimed at (among other things).

It would be nice to have some explanation in the documentation
how your implementation differs from the simulation framework
given in the purple book and why.

A Morphic or otherwise graphical animation using your framework would be 
nice.

In the citation list I would add some more references. Implementation
of your stuff done in other languages; other simulation frameworks
done in Squeak (e.g. Diego Gomez Deck's).

Generally I might consider using your framework some time in the future
(e.g. for teaching about simulation). However Morphic as a whole may be
as well considered a simulation framework (with a clock ticking and 
trigger methods, so I would probably look into that because simulation
most often means as well visualization.)
