Why you don't have curve line tools?
Bezier curve line looks nice on maps, but have no meaning in case of geographical coordinates. So we will never introduce Bezier as new tool as Polyline. But this doesn't mean that you will have never chance to see good looking bezier line on your maps. We are thinking about creation of bezierization filter (similar to simplification filter). That will be converting/simplifying polylines to bezier curves.
