Currently if you're using some VIs with the 16 contact pane (five columns, 1st & last with five contacts, middle ones with two) and some with the very common 12 contact "4-2-2-4" pane, if you try to line things up horizontally with an error cluster along the bottom and a refnum or such along the top, you get all sorts of messy looking kinks in your wiring. This could easily be fixed:
The edge contacts on 5-2-2-2-5 shouldn't be uniform in size. Instead the top and bottom ones should be the same height as on the 4-2-2-4. The middle three will still be decently large, the same size as the edge contacts on the 20-contact 6-2-2-2-2-6 pane. And now everything will line up nicely.
