You do realise that the Alt and Amiga keys are swapped compared to a "real" classic keyboard, right?
Was that an option that could be configured?
They write about custom layouts and "useful remaps", but I don't see anything in their ordering system for the most common remaps like swapping "GUI keys" and ALT-keys (it's not just Amiga, Mac keyboards are the same), or swapping left ctrl and caps-lock.
