Hi,
the algorithm is configurable, so you can define attributes and defaults
positions as you want.

I have some questions regarding your desired behaviour:
  - what's the difference between "180º" and "mirror", so why do you
place the attributes on the top left or on the bottom left?
  - same for 90º and 270º. what's the reason behind placing the
attributes on the right or on the left?

Attached is a scheme file with the a close configuration to your
preferences. It's not exactly as you want, because it places the
attributes always in the (middle,top)-left of the symbol.

Load it when running gschem, placing in your gschemrc:
(load "path-to-this-file/attrib-positions.scm")

I told you the algorithm checks if the autoplaced attribute overlaps a
pin connection. This is disabled with this configuration, because it
doesn't work quite well with stacked attributes (currently it only moves
the overlapping attribute, not all the stack, so you will get
overlapping attributes).

Check if this is closer to the behaviour you want. I'll try to improve
the algorithm for stacked attributes when I have some time.

Regards,

Carlos
