"Along with the more deformers, better deformers idea proposed already, there should be the ability to dynamically control the weights that drive them. A suite of utility nodes that could be used to store painted weight maps, generate maps (eg. via something like measuring a mesh's change from a reference mesh or normal angle changes compared to a vertex's neighbours) and manipulate them. Using nodes to blend, layer, smooth, remap, grade, transfer, clamp, multiply, mirror (and more) weight maps and plug them into various deformers would allow for complex and advanced deformation effects that just aren't possible right now."
