Not at present, which is actually a mistake - I meant for this to be
switchable. The basic problem is that the "smart selections" require the
complete interpretation of geometry restraints, which is not fast enough
for interactive use in most cases. The graphical selection editor is
cheating by guessing the connectivity from interatomic distances, basically
the same thing that PyMOL does. But that limits us to a subset of
I'll see if I can quickly add a preferences setting to toggle the method
used to interpret the model.
