Spline Extrude, Spline Surface

Some requests about these StreamLine Tools:
-Spline Extrude
-Spline Surface

First, add pleas option to Flip Polygons.

Second, Spline Surface, now when you run it you can not see segments, so you scroll wheel and can not see how much segments you have. Only after applying edges become visible.

Third, can you pleas make Spline Surface, to start from control points(segments amount)? Now you have to scroll MBW to 0, like in help said - use conntrol points, scroll segment value down to 0.
I found that most of all I use this settings and it is very unconvenient to scroll every time.
