I think it's annoying that every object that I want to apply a 3d effect to already has a 50 pt extrude depth and axis rotation by default + preview option checked.
Sometimes it takes forever to render the preview for something I don't even want, but the preview is checked by default so it immidiatly starts rendering when I open the effect window.
Would be great to open the Extrude & Bevel window with zeros in every field, saves a lot of time, especially when working with complex objects.
