When dragging an object from its place and before it is placed in its final position, we see its shape moving around with the mouse. However - we don't see the projection of the moved shape on the ruler. We _should_ see it, because that helps us place it more accurately: The (horizontal and vertical) rulers should display either a shaded range, or the boundaries, of the object being dragged.
Any reason the 'Helplines While Moving' is insufficient to task? Can already be exposed with grid and snap grid, and the guides extend to rulers (horizontal and vertical) when shown. The object guides do not affect the ruler layout until the Shape's text element has edit cursor focus. And the ruler will respond. Don't gain much for the effort to "show" object edges directly on the ruler. Likewise object center as requested for bug 154015

I'm not sure what you mean here also. How does this issue relate to editing? > Don't gain much for the effort to "show" object edges directly on the ruler. They are _already_ shown - except that only the original object boundaries/edges are shown. You gain about the same from showing the new boundaries as from showing the old boundaries. Which is letting the user consider the positions on each axis independently of the other axes. If Impress or Draw let you create rules by dragging from the rulers (do we have a bug for that feature?), then the benefit would be more limited, but we're not there. I find I'm missing this when positioning objects.

I do not have problems getting helplines.
Helplines are efficient to position objects with some accuracy. To achieve pixel-perfect positioning you need to enter exact values anyway. => WF (actually WFM as helplines do the trick)
