Hi,
I just picked up Zest and in two hours integrated it with our data model
(by mapping the IWorkBenchAdapter to the IGraphStructuredContentProvider)
and was dragging and dropping data all over the place, WHAT AN AWESOME
TOOL!... now that kudos is paid to this fantastic tool:

I want to be able to control the zoom of the graph on my data (sometimes
thousands of nodes). The radial layout zooms out nicely when the data size
gets huge, but I want the user to be able to zoom back in (even something
as primitive as adding a keyboard listener on '+' and '-' (though a small
highlevel view would be cool too!).

Does anyone know how to control the zoom? There is zoomAt method on the
GraphViewer class, but it doesn't seem to do anything, there is a
ZoomManager but it's hidden internally. How is this meant to be done?

Any suggestions on being able to zoom in and out would be great.

Cheers,
Will.
