If we leave the pin numbers as is (starting at 129) we can avoid doing the obsoleting, but as noted I would prefer to renumber the pins. We could chose to move all the ground pins to the bottom and all the power pins (overlaid to give a single connection point) on the top if that would suit better. I like this because if I am debugging on the actual board the schematic pin is in the same position it physically is on the board which makes it easy to find in schematic. That can be confusing to a new user and I believe is the main reason for using overlaid pins. The downside to this is that Fritzing will not let you make a connection to a ground pin if there is already a connection to the ground net somewhere else in the same net. The overall layout mirrors breadboard (which I find more useful when debugging, but others may not like!) That means there are no pins such as ground overlaid to create one connection. The pins are renumbered to start at connector0 and the xml numbers are rounded to 1/1000 of an inch.
