Poor muscle action description

I am very disappointed in this app! It only has very elementary muscle action/function. This app has little value for sports medicine and exercise physiology professionals. Integrated muscle function must be added for this app to be of value to me. So much potential here and I am sad to see it fall short! For example the Lats do much more then shoulder adduction and extension... How about internal rotation of the shoulder, increases stability of the LPHC and aids the glutes in the force closure mechanism of the lumbar spine.
