AlignViewToFace

Aligns the perspective view to the face that is under the mouse while keeping the distance to the selected object (the distance will pretty much the same as between the view and the face to align to). It does not matter if the object has modifiers applied and the view will not be distorted into some strange rotation but kept aligned to the world axis. Especially useful when a toolmode is active - like the cut tool - since viewport navigation in those cases is restricted.
