Originie is an add-on for manipulating the pivot's (the origin in Blender lingo) position with ease. It comes with bunch of tools that would let you move the pivot around as you "wish".

I really like it. I’m already using it frequently, and it does what it promises

I’m very very happy with all your addons, they all deliver much more than I expected and are of far greater value than their price
