• If you would place the LED indicator terminals after the case structure, you would not need local variables.
• If you switch the state before the case when stop is pressed, you don't need the lower shift registers.
• A +1 will rotate through the states. All you need is a single enum constant.
• An example program should have the front panel and diagram aligned with the visible window area, not offset and partially hidden.
• This entire thing could be done with much less code (code in image below does exactly the same thing).
• Latch action booleans should use buttons, not switches on the front panel.
• Typically, the color of structures should not be changed.
• It makes no sense to spin the loop as fast as the computer allows.
• In my example, the real state code would be in a separate case structure parallel to the second case structure. This way the right LED lights up at the same time when the state code starts executing.
