Putter/shot pal on/off button is a great additin IMHO. More so for those that use it but don't have the unlimited option through their CC. If you have a tap in putt or a full power shot you don't need it and it will be an easy way to save those wasted hits.
However, the bright coloured button and it's placement is a bit cumbersome, although I at least appreciate that it isn't near the ding line.
My suggestion would be to put a radio button within the shot type selection menu.
