Well, this isn't really the way that effects are meant to be used.
You're asking for a pallet, which honestly isn't available.  In order to
do multithreaded, we can't assume that anyone has a golden version of
the document anymore.  Palettes are on the roadmap, but until the DOM is
available, I'm afraid that they are impractical.  We could make the GUI
refresh, but would have to force you to be unable to edit the document
(which makes the GUI refreshing not that useful).
