v1.0.1 adds the ability to easily convert between left-handed and right-handed configs.
See this post which explains the subtle implications of naive mirroring.
With Cool Hand, the following additional changes were made by hand after the initial mirror.
Cool Hand left hand
N 00M0:080 :# Keyboard LeftArrow
N 00R0:079 :# Keyboard RightArrow
Cool Hand right hand
N 00R0:080 :# Keyboard LeftArrow
N 00M0:079 :# Keyboard RightArrow
I hope together with the implementation of this feature request will encourage more users to experiment with different layouts.
