Nice!

But also quite different. Well, I am wrong in the assumption they
don't use floats. They us CGRect etc.
But there is indeed not equivalent to NSCell. And target/actions are
handled completely different.
So, they can NOT use standard IB and NIB files...

No. I think the differences are too fundamental to use
compatibility_alias. E.g. the target/action approach. Backlight is not
available in mySTEP in the NSWindow class but indirectly through
something that appears to correspond to UIHardware.

Yes, but I don't believe that it works.
