You can try this one I wrote

This one allows you to scale, but not move. Also doesn't touch the side ones [I've never found myself needing the side ones at all]
The problem with moving the default action bars is really that the default UI has A LOT OF CODE to constantly move it back on just about anything combat related that you can imagine, and fooling around with it breaks the action bars easily.
