[REQUEST] Addition of some features

[RavenStryker]

I have found this blender plugin absolutely amazing for filling in the empty space for terrain when making race tracks. I know it has been a LONG time since this has seen any updates, but I figured it wouldn't hurt to ask and see if they were able to be done.

1. I'd love a feature that would smooth the vertices of of the curve with the inner generated vertices. Currently there is a very HARD dropoff if the surface isn't completely flat. It reqires a lot of manual manipulation to make everything flow a bit smoother. See example below.

2. This may already be a feature, but I haven't figured out how to utilize it if so. I'd love to be able to fill in the area only between two curves if that makes sense. So if I have an outer circle curve selected, and then an inner circle curve as well, instead of it filling in between the two circles and also inside the smaller circle, if it could leave the middle empty, that would be ideal. This would allow me to create tiagulated terrain between the outside of the track surface the end edge of the viewing distance. In the current state, I have to do a lot of fanagaling in order to remove all the additional edges it created inside of the inner curve for the track surface.

Thanks in advance for taking the time to read this if anything! I appreciate all the work that went into this, it is amazing for what I do!
