The pads are indeed numbered in order of creation. In my experience, you
can simply renumber the pads in the footprint file. Just make a note of
how the numbers should change from what you see in PCB beforehand.

The best approach is to number pads during creation. Each line that is
to become a pad can be assigned a number by pressing N while hovering
over it; just enter a number as the Line Name.


When dealing with structural metal parts such as mounting tabs and pins
on connectors, I usually assign these the number 0 (zero) -- although
the gschem symbol should have a corresponding pin if these parts are to
be connected to a circuit net (usually GND). Perhaps other people use a
different approach here?


Best regards,
