Right.  next time.

Right.  So there would be an option in whatever widget to call FS to get
a pseudo feature highlight if a FS service is available ?

I guess you are referring to
http://geoprisma.org/samples/shortcut/activateresources/index.php.  I
still think the user should be given the sense of *what* the road he has
just zoomed to is on the map.  

I've seen examples with a bunch of small polygons and, depending on the
zoom level (an option), the one in the center could be a lot of them.
Without at least an option to highlight or mark, just zooming in to a
feature from a shortcut or an InitialView seems to me like unfinished.
It should be clear to a user where to click for a QueryOnClick once he
has zoomed in.

Right.  That's a point in itself.  There is a GeoExt widget/example that
does that IIRC.

As an option yes.  But I would default to no zoom because the zoomTo
would be a function of tolerance and it could be pretty staggering to go
from zoomLevel 1 to 16 (and then potentially zoom back out again for
another query).  Think of it, it could be a button in resultExtGrid ?
