Hi Pilou - for grid scale this isn't very clear, since grid scale doesn't just copy an object along one single path, it can go in the x, y, and z directions.

I'm afraid this one may have to wait for a while... I agree it would be cool and good for seashells, but not quite so practical in general.

I get a little worried about adding too many parameters on things. Adding parameters can add to the power of a tool, but there can get to be a certain point when there are so many parameters that the ones that need to be used most frequently become obscured in the big list...

Maybe this would be good to have as a sort of "super-array" special plugin later on at some point.
