Today, if we want a FOR loop with a fixed number of iterations, we need to wire a diagram constant to N. We could probably save a few clicks if we could click on N and type in an integer directly. It would also unclutter the diagram. This should of course only work if N is unwired.
Of course the N-Box would grow to the right to accomodate all digits
To later change the loop back to "normal", we would type N into the box or simply wire something numeric to N from the left.
As an example how it could look like, here's a simple cross product implementation (Yes, I know, LabVIEW already has a cross-product, so this is just to show the idea!)
