Thank you all for your welcome messages!

I am very glad that you appreciate my scripts.
In principle, I am updating all my scripts with the main purpose of making them fully compatible with GIMP 2.8, while keeping the backward compatibility with earlier versions. Furthermore, as regards some of them, I proceeded to add some new functionalities.
As for the "Drawable Multiplication" script, for instance, I can already tell you that I added the abilities to scale and rotate the duplicates incrementally when the original drawable is a layer, as well as the option to place the layer copies in a new layer group. I am also thinking about the possibility to give the script a more evocative name.
