Module support?

I agree with Kilishan 100%.
Your controller methods should be relatively thin.
Controllers calling controllers sounds like you are doing something wrong? Don't be afraid of writing a library or 10.
That way your code can be used any where (in 50 controllers if it needs to be used) and then controllers aren't calling controllers to get at certain code which you only wrote in said controller.
