Feature request: duplicate and sort watch faces

I'd like to be able to duplicate a watch face. Example: I set up a watch face with lots of nice fields with a white background to use in daytime. Then I'd like to lave the same one with dark background for night use. Duplicating an existing watch face and just changing colours it's easier than creating a new watch face from scratch.

It would also be nice to sort the order of watch faces, just like other menus can be sorted...

Thank you,

Marco
