I added more movement to my buttons and improved their shape. They are now superellipsoids that morph into circles and back when clicked.

More buttons have been added, also. These buttons are used for scrolling. They differ in shape and movement, being triangles that move to the left or right when clicked.

I also created "metafunctions," which contain all of the native functions of a specific type inside them. They can be opened and closed, providing drop-down menus of a sort.

Other improvements are the overall layout of the function, allowing one outport to have multiple connections, and being able to connect the outport of a function to the inport of the same function..
