So, I don’t know if anyone has created something like this, I just created because I needed it and I couldn’t find a simler way of doing it…
As I was sick of creating empties and rotating them, applying location to objects and etc, I created this:
Update 15/6/2013:
Fixed issues with Blender 2.67b and added an Empty Checker…

Instructions:
a) With one object: add an array modifier, put the number you want in the cout box and finally press Object > Circle Array and voila!!! You will have a new empty and the object will be duplicated around it’s origin…
b) With two objects: add an array modifier to the first object, put the number you want in the cout box, select with shift + RMB the second object and press Object > Circle Array. You will have a new empty and the object will be duplicated around the origin of the second object!
Well, I know that it’s very simple but personally I find it TERRIBLY useful and I hope you find it useful too.
