I agree wholeheartedly with your sentiments John - I use one finger chords with the left hand just so that I can put more feeling into the right playing cos I don't have to think about the left hand at all...
Equally I use technicord, for the same reason, just one finger on the right hand produces 3 harmonised notes.
Again all my changes of variation for each song are panel memoried sequentially and linked to my foot pedal so that a tick on my sheet music tells me to merely tap the foot pedal and the variation changes through the panel memory.
All part of your keep it simple philosophy so that I can concentrate completely on - I believe the word is - expression.
