The Corporate theme now includes an EC area located in a fixed position at the bottom of the screen that can be turned on or off on a per page basis. I have also added some really nice CSS3 features to give the theme a little extra eye candy.
The Corporate theme includes the following:

ability to use custom headers

5 width options

5 header height options including one that will completely remove the header

split (dual) navigation system

an all new file sharing page

EC ready

and much more
