For anyone looking for an easy way to move the clones seperate from the main as group or individually, with the G15 it seems pretty easy.

I've set up the bottom group of 6 keys to control slave movements, the middle bottom key is the /follow main key, the other two bottom keys turn the slave(s) left right, the top row moves forward and left/right. The keys are bound to empty bar space on the main to avoid them causing the main to do something unintended.

With multiple slaves you could reverse the movements on the odd slaves to create a formation, i.e. slave one moves forward and right, slave two moves forward and left when the top middle and right key is pressed.

Hope that makes sense.
