Hey mate, thank you and fair points.
I'll update the project within the next 24 hours to include an offline version - with at the very least some form of text box or output you can use to easily save the configurations (if you intend to make a lot at once).
Update : The files now contain an offline version with a text box that lists the assets in use. In the near future this text box will work both ways so you can load previous formations back into it.
