Reshaping form using control points?

Hi Michael,

I really hope you do it. It's so useful to directly push and pull shapes when testing out forms, and I feel there's too much design separation to do that with the technique you showed. Is it worth me adding a vote for it in the top 5 v3 feature thread?

I find that with many lattice cages, they're visually obstructive. Do you have an idea of how you'll implement it? It would be great to hardly notice that it's there, but just enough to use the control points. And perhaps the connecting lines could be nearly transparent, or maybe the visibility could be user specified.

Thanks
