Good work, thanks.

This should be fixed.  The bonobo nature of the printing is left
over from gnumeric's early status as a test bed for Bonobo.

By this I assume you mean undo/redo for object property changes.
Your recent work to enable support for move/resize/create/delete is
a good starting point.  However, the next stage may require a Bonobo
interface akin to Zoom for remotely managing an undo/redo stack.

I've got some rough work in my tree that will implement persistence
in the standard case for Bonobo objects.  However, all of the
sheet-object work should be viewed as a work in progress.  As you
have seen thus far there are still lots of questions remaining to be
answered.  Many of which will require gnome-2.0 features.

    - Clipboard support
    - Configuration undo/redo
    - Better layout and semantics for menu/tool-bar merging
    - How to handle them for the non-gui build
    - Which structured file format we'll select to store them
    - A generic mechanism for storing dependencies from the objects
      back to the workbook.  The Dependent mechanism gives us an
      api, but there is no generic persistence mechanism.
    - How to address dependencies from the Sheet out to the objects.
      eg we will want access to the fit parameters from a graph back
        in the sheet.
      I've handled this for graphs only for the case of vectors.

Thanks for your continued work in this area.
