Wouldn't mind a basic run down on what it can do and what it cannot.
Aside from the initial information, when it was first announced here I've essentially had no information on GCP.

One boxer, who moved from Pwnboxer to IS Boxer mentioned that they had used Game Commander Pro in between the other two products, but IS Boxer was the product they eventually settled on.

It would be neat to have someone who actually used it, talk about it a little.
