Can we get more customisation please?

The world is not America. When your version of English was created not really all that long ago to separate Americans from the British who had ruled over them they often just changed small parts like Z for S. While the American spelling is newer and common in use it's not the world standard for English and simply comes from the US.

I think most of the changes came from the lazy spelling or spelling made simpler/easier. Color - colour, jewelry - jewellery etc..
