Core XView functions should get an update to support more object types. For example, any xView that requires an editable_poly or editable_mesh should in theory be able to understand any other GeometryClass object--especially those that use editable_mesh. For those cases, the XView should simply be able to use the geometry's mesh property.
For example, I need to easily find objects with open edges but I need the class to remain the original class because of the need to keep the data in extra plugin classes. It would be very helpful if the Open Edges XView could work on any geometry class. Same with all other XViews that work on editable_mesh.
