Hi Pior, and also one other note - one reason why it's a bit different in MoI that this kind of constrained x,y,z movement is a snap instead of only on a "manipulator" is that you also can use the same thing while drawing curves or lines to make the current point that you are drawing to be in a straight line from the previously placed one.

In MoI you can move objects (either control points or whole objects) by just grabbing the object and dragging it, you don't have to drag on a manipulator for movement. And then when straight snap is turned on it will help you to constrain the drag motion in a particular axis direction. If you have it turned on while drawing it will help you do the drawing in a particular axis direction... Basically in MoI the same mechanism works for both drawing and also editing, while a manipulator mechanism is something that sort of only works for editing only.

In 2D views there is also an edit frame manipulator which works more like a 2D illustration type manipulator that is a frame that goes around the outside of the selected objects, that one can be used for quick rotation or scaling in 2D views. But for movement you just drag directly on the object you want to move in either the 2D or the 3D view.
