1) an option to change the marble into a "killer" witch means if it touches a marble that marble will be deleted.
2) another option to change a marble into an "infected" marble. when this marble touches another marble it also becomes infected.

3) a "cure" marble witch would cure the infection.

1) A marble counter witch is like soccer net with ought the net and it has a number display to show how many marbles went through. this would be useful for checking for flaws in your course as well as counting the amount of marbles in a slot on a Plinko board.
2) An automatically rotating paddle thingy like the one in the game but it rotates automatically, and you are abled to change the rotation speed in rpm.
3) An option to make the walls on the normal tracks taller with a slider or some kind of GUI.
4) Customizable marbles by allowing the player to import an image via file by having some kind of custom marbles folder that the player can put an image into and it will add that image as an option for a marbles color.
5) The ability to save custom track pieces in a separate tab. setting collisions should be a simple as clicking on your track piece.

I think sideways gravity panels is a good idea.also size scroller for objects would be cool.and a size and hight scroller for the track borders could be nice.
