I did not because original drawing in GTA02 and in datasheet only label the uppermost pin. :) Which is understandable, because it's redundant information. It's
mainly there for power purposes.

Again for the same reason. I also did not like to name it that way. I do think "ON" would suffice though. :) Otherwise we'll start to change "EN[able]" pins to
"EN[able]/nDIS[able]" :) Some manufacturers seem to label pins in a very weird way - why the heck they name "S2" the input anyway? I got so confused that I had
to read datasheet three times so to be sure I was not missing anything.

Yes. I'll update. That will make DRC happy.
