before I post things in the wishlist wiki I thought I'd better find out if some of these things are possible?

1. is it possible to hide selected points on a spline? I have a lot of points on a helix that confuse me when editing from the top view looking down the barrel.
2. is it possible to transform/manipulate/scale splines that make up a surface? i.e. I create a revolve of a spline, the resulting object has feature curves that define the surface. I can select those curves but can't move or scale them.
3. is there any way to bend a surface after it has been constructed flat?
4. is it possible to pick the object or point the camera revolves around? like a focus point. this would help a lot when zoomed in on a part of an object.
