Have you ever wanted to place a probe on a loop iteration counter? I can't tell you how many VIs I have with a wire from the iteration counter to the loop boundary just so I can put a probe there (Maybe a pop up iter. count would suffice). Or probe an output terminal on a VI that is not wired. I know you can open the VI and put a probe on the wire but..
There are probably more cases.
Minor issue, but since we have a chance to ask..has been bugging me for about 20 years now.
