If I may chime in,
I really like 3dcoat’s implementation of the the tool. https://www.youtube.com/watch?v=I3UifVSt_6A
It does some really nice things with selection type, just like nomad.
Something similiar would complement nomad’s tools very nicely i think. Used in conjunction with masking and gizmo you can get a lot of creative uses for it (like mimicking parametric/lattice deformations like taper, squeeze, bend, twist etc.)
just my two cents.
