I wonder what other players think to the numbers used for house building...

To me, I'd like them reversed so that '1' was build SW corner, '2' was S wall etc. This would reduce keystrokes, assuming you are building from inside the house (which saves on lugging wood around).

What do you think?

Making the keys correspond to the Numpad numbers?
Sounds like a valid suggestion, assuming Numpads are identical worldwide.
I actually have no idea either way about that though.
