no,
I may have described it wrong.
This is not at all what i wanted to say.
I'm not for aligning ALL resistors, this is useless.
But i am very for aligning the parts where it doesn't make any change in
trace length.
Often the traces get much shorter by proper alignment.
I don't place the parts like i want them to be arranged and after that make
the routing.
I place the parts so that routing is easiest and simple and that the pcb is
as small as possible.
(by alingning the parts a bit the pcb actually gets smaller).
Hope that makes more clear what i wanted to say.
