  We explore the possibility to include small-$x$ dynamics effects in the
parton branching (PB) approach to transverse momentum dependent (TMD) parton
distribution functions. To this end, we first revisit the PB method at leading
order, presenting a new fit to inclusive-DIS precision data, and performing a
numerical study of the dynamic soft-gluon resolution scale. Next we investigate
the effects of modified CCFM kernels, including both Sudakov and non-Sudakov
form factors.
