Thanks Michael,

Whoa! You actually could foresee a "Cage" deformation tool in the future? ...that would be the next best thing to Flow.
Would we be able to re-orient the "cage" in 3D space separate from the object?

Yeah, didn't think the Rotation and Shear types were too related.
And yes, I tried the Flow method of shearing today just for fun, works great!

However, as I've seen in a demonstration (by another app), having a Shear tool that works like MoI's Rotate and Move have the potential to yield ungodly amounts of precision.
Plus you could use it within a structure, such as on a selected bunch of control points, or use it just on a shape, say in the middle of a Loft while it has history.
