It would be really useful if you could implement an option to move/alter the rotation point of a selection/object in the transform tools.

Ideally it would be great if you had the choice of picking a point on a box diagram, much like you would do in Photoshop or Illustrator etc and having a free choice to position it wherever you want.

I think it would make certain transformation so much simpler as the current 'centre only' approach just leads to more repositioning afterwards in a lot of instances. It would allow repositioning of things like arms or objects with joints less faffy too as they could be rotated from the correct point from the outset.

And layer masks (prod, prod)
