Hi Anis -

> could you give us a illustration in gif format ?

You can see something similar by pushing the "Reset" button that is at the bottom of the 3D viewport, which centers the rotation pivot point (the "target") at the center of the bounding box of the selected objects and also fits them to the screen.

This new script does nearly the same thing, but only does the centering part without doing any "zoom to fit" step.

I don't think it is of much use to very many people, just something that Nick had requested for some particular purpose.

Generally I would expect for people to use that "Reset" button instead of this.

If you need to see an illustration of the Reset button, it is covered in one part of the tutorial videos here: http://moi3d.com/1.0/docs/tutorials.htm
