In the 'string switch' there is no option for if 'no match'. So it goes thought the list and the string is not there, there is no 'else'. this should be added.
Without a 'else' this is not very usefull. Once added, you can compare to a series of things and if none are matched, have a default transition to go to. An example is I am trying to map a joystick to keys. the player can select anything, but I want to limit it to letters and numbers (this is just an example). I could put in the letters and number and if he selected something else, the 'else' would be triggered. Then I could tell him to select another key.
ALSO: the 'int switch' and other switches should have an 'else' in them as well.
