Connectors often use a sequential pin numbering so we don't follow this rule. However in "chip" symbols it becomes quite clearer and cleaner if you have all GND
connections on the bottom. Imagine looking at a diagram for example of a common-emitter amplifier where VCC is at bottom and GND at top. :)

No, keep them sequential. Unless someone disagrees.

That will also make schematic a bit cleaner. Thanks.
In SVN now also.
Thanks again for your work!
