Most of my wishes already are on the list but to let you know:
1_More control on fillets, editable, removable, but also elliptical, and with different weight for each side like the blendsrf.
2_More on mesh, everything it’s needed, not only for checking but, mainly for drawing, like bridge tools and all the waverbird tools.
3_Physics engine direct on basic Rhino like Rhinophysix, not only in gh like kangaroo.
4_more control over the number of cv and spans of the srfs
