'KEYING' the pin outs

My 2 cents worth, is to have every 3rd black pin out to have the corners rounded, then on the silk screen, show the form of the pin out socket. When inserting wires, the silk screen and the pin out will match, won’t be so hard to locate the correct pinnout.

I can’t figure out how to post my drawing-sorry
