Spring dampening for Suspenden / Swinging Coasters and Track compensation in h/v direction

[T-Mampf]

It would be cool if there was an Option or trackpiece that allows the traincars to swing with less/more friction. I build a fast winding track for Gold fever but the cars litteraly didnt move through that element. An element like the unlock Rotation for the rotating wild mouse where u have a friction slider or so was something i thought of. And that track compensation, that slider that alows to build track with an Offset, would be also cool to have with every Coaster becouse it is supereasy to build airtime ant vert./hor. heartlines. That Offset would also be nice to have in horizontal direction.
