I have added it to the https://github.com/sketchplugins/plugin-directory repo, so this can be closed

I actually changed the repo name to https://github.com/delighted/sketch-duplicate-to-new-artboard

Here is a description for the list as well...

"Duplicate the current selection(s) to new artboard(s)."
