I would like to see a Taper tool. Nothing too complex. You would only be able to set the taper amount along the sides of the block and not randomly in the middle. This would be helpful when working with primitives. I would think taper would be derivative of the scale tool that Asset Forge already possesses since a taper is essentially just setting a scale along one plane at one end point while not scaling the same plane at the opposite end point, then the middle is scaled accordingly.
