adding extra buttons in maya

Baking all your animation down all the time? I'm not, but people I know are, true story. Recently I was asked why a bakedown script wasn't quite working properly, and it turned into making a new button in the anim layer tab in maya to merged all layers :p
Here's the code to just bake down your layers;

 animLayerMerge( `ls -type animLayer` )  

But... why not just add that into the main maya ui? It's easy!
