I am busy with the developement of "breast movement" for G2 Females but will be called Breast Control. The glute part from the G&B product on Genesis1 has already been released called Glute Control http://www.daz3d.com/glute-control-for-genesis-2-female-s-and-v6
At th.is stage I will not be redoing Toe control as that product was extremely niche and didn't do very well on the market. In terms of fat pinching and fat collisions, that can be done but it would have to be for a specific shape via JCM's. Downside to that is no figure blending or mixed shapes because it would break functionality. To make something universal in that regard is extremely difficult because you would need morphs to cater for every possible contact point of every possible shape, and that means 1000's of morphs lol.
Best bet is to set the figure itself to collide against an object and place that object it in different places and do spot renders of the collided areas and merge in postwork. I normally use a ball or something like that and adjust it's scaling depending on how I want the impact to look. Then I set that ball object to 0 opacity and render the image with the contact point.
