@enoch85 yes, I know. It is just another additional apps script but I promise this will be the last one for this folder for a while.
And this is already much more stable and has much less dependencies as the pdfdraw app, so I think that it fits into the additional apps menu quite nicely. And yes, I think this makes a nice and also a very welcome addition to all the other apps, hence I've created it 😉

This script is finally ready and was successfully tested on a NC21 test-VM :)
