I believe so.  We started out with the form being embedded in the
FormBuilder "mocked-up" to look like a top level window.

I think I remember that after we switched from using the "embedded
form", a toplevel window was used.  I believe I was attempting to make
the window only movable within the FormBuilder, to make it seem that it
was contained by it.  It obviously didn't work.

Agreed.  The plugins have trouble.  What started out looking like a good
idea became a problem in interconnectedness.  We definitely need to
revisit how all that works, too much information is required right now
for an outsider to do anything with the plugins, and that includes
modifying their configuration.

And speaking of 2.0, I agree that we should rework the XML usage.  I
noticed your response to bug 744921.  When Guido was written, XML::DOM
was the easiest option we had.  Now there's lots of better options,
several of which are much more lightweight.  I'm partial to the SAX
(using the gtk xml libraries) and XMLWriter options myself.

I can get rid of this error by doing a 'delete($geo_params{'-in'})' in
TkWidget::Basic.pm. But that is just soooooo kludgy. Trouble is I can't
yet see where this parameter came from 8-(.

Wanna steal ZooZ and convert it to a Guido plugin? 8-).
