Hi Mike, well shearing and rotation are kind of different operations, so I'm not so sure about grouping it under rotation like that...

I think that there eventually be a "cage deformation" tool under Transform > Deform, and then you'll be able to do a shear by doing a minimal 4 point cage and then sliding 2 upper points over.

You can get that same effect right now by using flow, draw a base plane using Draw solid > Rectangle, then duplicate that and turn on control points, shift the upper 2 plane control points over to make a sheared rectangle, then you should be able to use Flow from the regular plane to the sheared plane to make a shear happen right now.
