This gives \"logarithmic\" W-algebra extensions of a fractional-level ^sl(2) algebra. We discuss crucial aspects of the emerging general relation between Nichols algebras and logarithmic CFT models: (i) the extra input, beyond the Nichols algebra proper, needed to uniquely specify a conformal model; (ii) a relation between the CFT counterparts of Nichols algebras connected by Weyl groupoid maps; and (iii) the common double bosonization U(X) of such Nichols algebras.
