Query: The big picture   We discuss the conformal field theory and string field theory of the NSR
superstring using a BRST operator with a nonminimal term, which allows all
bosonic ghost modes to be paired into creation and annihilation operators.
Vertex operators for the Neveu-Schwarz and Ramond sectors have the same ghost
number, as do string fields. The kinetic and interaction terms are the same for
Neveu-Schwarz as for Ramond string fields, so spacetime supersymmetry is closer
to being manifest. The kinetic terms and supersymmetry don't mix levels,
simplifying component analysis and gauge fixing.
