Can you post a screen-shot showing the issue please?
The coordinate box should be expanding to fit the content in...

As for no rules - (separate bug / feature request if you want to persue this please), It is probably because they would take up screen real-estate otherwise useful for drawing on the board. That and the fact that GTK doesn't have a non-deprecated API for drawing them, so we'd have to copy+paste or NIH the widget code. I don't recall the old (deprecated) GTK ruler widget being any good though.
