Hi Andrei,

> Also Michael, it will be great to not only extrude but also shell,

That is something I'd like to explore in the future. But it may be difficult to put in shell because shell already does something else when given a face sub-object selection, it uses those selected face as the openings for the shelled result.

It might fit in to offset maybe something like a "build side walls" option for when offsetting a face, that would be for doing pockets or protrusions using an offset type construction rather than an extrusion type.

These kinds of things will probably work better with "face transforms", similar to what I described above in the reply to PaQ, that's where after doing some edit on a particular face like moving, rotating, or scaling it, the surrounding faces are extended and reintersected with the updated face. It's something that I want to work on in the future.
