Pickup at 135 degrees, and drop at 45 degrees.

And the distance from 1 to 3x.

This goes against the "Simple" part of the "Simple Configurable Inserters".
Will not be added.

This is one of the most commonly used configurations. And it does not contradict anything simple: length constant, angle 90 degrees. But, my job is just to suggest.

This mod is purposefully designed to not allow abstract angles other than 90° mentioned in the "Why?" section of mod's description.
The pickup position is supposed to always stay directly "behind" the inserter.

In this case the inser's pickup angle gets changed.
