Need Some idea

Hi every one,
we bonoboized partially gtkmathview,a GTK widget for rendering and
editing MathML markup.
Well for now we have just implemented the Control and PresistFile
interfaces,I would like to ask if some one have some idea about other
intresting interfaces i can implement or have other nice ways of
combining this components with Bonobo-aware applications.

Thanks ...
