Please add these 3 coaster types. The 4D free spin coaster is a super awesome design as well as the zacspin/coasterball was also a cool variation that would be awesome to have in the game. Arrow suspended swinging coasters are also a ton of fun to make. The S&S axis would also be extremely awesome to work with and sadly has only been implemented in one coaster game that really didn't make it possible to create layouts with it easily due to the banking system not recognizing a 360 degrees banking and 0 degrees banking as being the same thing.
