volant: Oh yes - an option for sure since I know some people like scrolling down past the board (checking the board to make sure their move is good) before submitting.

For me, as long as the board does not "shift" while the page loads, I've already looked at the board when I made my move - and ready to submit and move on.

If I know the submit button is going to be in the same spot every move, it would speed things up a lot - letting me put my mouse where the submit button will be and being able to click as soon as it loads - without first waiting for page to load, then scrolling down the page - then looking for the submit button - then finaly clicking on it.

Yes, Optional of course.
