This connectors tool has a fairly limited use, but it can save us some work when creating diagrams.
If we have, for example, two rectangles, we select the connectors tool and click from the center of one object to the center of the other. The tool will create a connector that will go right from the edge of one to the edge of the other, without having to adjust it by ourselves.
On the other hand, you can choose connectors that border the objects, that cross them or that are orthogonal:
In any case, just as in the introduction I was saying that Inkscape is much better for creating graphics than PowerPoint (as in fact it is) in the case of organization charts, I would recommend that you do them with PPT (using SmartArt), because it has functions standards that are valid for most of the cases that we need and are easier to work with.
