Topic: object "visibility" attribute
I think it would be good if all objects had a "visibility" variable that we can control from our sketches. Obviously the the object is invisible it should not be touchable, i.e. not work.
It could be optional, and if not asked for don't generate the variable for it in the code.
There are many times I have wanted to do this, for instance multiple objects on the same area of the screen, I can use their "visibility" controls to select which object appears.
