I would like to be able to clone a results plane and/or copy settings from one plane to another. For example, if I had a plane set up with vectors, shading, etc. at X=0, then I could clone it align it with Y for a consistent look. Another use would be to make multiple cut planes (X=-1, X=0, X=1, etc) quickly with the same settings.
A similar idea I suppose could be applied to isosurfaces.
