This relates to animation, that was discussed on kepler-dev about a week ago.
A couple of notes, which are my personal opinions, not nessarily the positions
of the group:

- "Feedback" means something specific in block diagrams and control system:
systems that are cyclic as opposed to acyclic.  So, we should be careful
in the UI about using the term "feedback".  I took the liberty of
adding "animation" to the summary.
- Providing visual feedback to the user about progress is very valuable.
We talked about providing feedback about how much data has been downloaded
by a DataSource actor.  This issue is probably a separate bug.

- We would need to be careful about enabling animation all the time.
For example, if an actor fires a million times, what do we do?  This could
slow execution down.  Thus, I'm not sure if bug should be fixed by
turning animation on full time.

- Currently, animation does not work for PN.  This should be fixed.
Is this a separate bug?

- Perhaps we can be smarter about what happens when when animation is turned on
and we go inside a CompositeActor.  Perhaps we could have something like
"step over"/"step inside" in the animation control window.  Is this a
request for enhancement?
