Intelligent design space

When tracing round a background bitmap (often zoomed in ) - it would be handy if rhino recognised when my mouse was off the design space and move the image accordingly - so i can continue drawing without needing to pan the view.

thx,

Have you tried 3Dconnexion 3dmouse? It helps me to navigate during some 2d/3d work, including tracing bimaps.
