Feature request: Copy/paste surface, splitting from surfaces

Two feature requests:

  1. Ability to copy/paste a single surface of a closed polysurface. Currently, attempting to copy-paste (using ctrl+c/v) a single surface of a closed polysurface does not work. If I use ctrl+shift+select to highlight the surface below, and then try ctrl+c, I get the message below. The only way to copy the surface is to run the copy command, or by extracting the surface first and then copy/pasting.

  2. Ability to split based on a surface that does not fully intersect the original object. When attempting to split an object, the splitting tool object must completely intersect the object you want to split. In the image below, I attempted to split the main box in half using the flat surface. Many CAD packages have the ability to split based on a surface that does not need to even intersect the original geometry.
