This entails the development of an algorithm for nesting triple-collinear splitting functions. It also involves the inclusion of the one-loop double-collinear corrections, through a $z$-dependent NLO-accurate effective $1\\to 2$ branching probability, using a formula that can be applied more generally also to future full showers with $1\\to3$ splitting kernels.
