Rule of Thirds Grid

I’m just starting to use Storyboard Pro to work on a portfolio for animation and I was surprised to 1. not understand the purpose of the grids at all and 2. find there were no helpful grids or area guides for the rule of thirds. Am I missing something? Is it really not used in animation unless the composition calls for it?

Thanks,
A newbie

The grid would be helpful when positioning or drawing objects and characters in a scene. This is a field guide which as some measurement for the movement of the camera or the object as well. However, this is commonly used for the traditional animation (especially on paper to digital) as for the measurement that in paperless animation where you draw directly in the system, this concept may not be necessary since all are visible digitally but it was necessary back then and still now on traditional workflow.
