Hi Ella,

That's the part that would not really do anything - dollying (instead of zooming) any of the ortho views along their same view direction wouldn't produce any visible change. This is for moving the view's eye point, not moving objects - moving objects is different since you can see the change to the object in other viewports, that is not such a problem.

The way object snap currently works is essentially a 2D operation where the points or curves closest to the 2D mouse pointer are targeted for snapping.

To do object snap with only delta type movements in x,y,z and not any central reference point would probably require creating something like a full 3D collision detection system... Which certainly would be cool but also a really significant quantity of work as well.
